2012-11-21ARM: zynq: Remove all unused mach headersMichal Simek
Remove empty unused mach/hardware.h. mach/irqs.h is unused because SPARSE_IRQ are ON by default. mach/timex.h is unused because of CONFIG_ARCH_MULTIPLATFORM. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Tested-by: Josh Cartwright <josh.cartwright@ni.com>
2012-11-21ARM: zynq: add support for ARCH_MULTIPLATFORMJosh Cartwright
The majority of changes are necessary to remove dependencies on header files within arch/arm/mach-zynq/include/mach: uncompress.h - Deleted. It is unused for ARCH_MULTIPLATFORM builds. uart.h: - Move uart definitions out of uart.h into debug/zynq.S, which is now the only user zynq_soc.h: - Move SCU address definitions into common.c. - Other #defines, such as PERIPHERAL_CLOCK_RATE, TTC0_BASE, etc, are unused and can be dropped Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Tested-by: Michal Simek <michal.simek@xilinx.com>
2012-11-21ARM: zynq: make use of debug_ll_io_init()Josh Cartwright

2012-11-21ARM: zynq: remove TTC early mappingJosh Cartwright
Now that the TTC driver has proper support for DT bindings, it is not necessary for the registers to be mapped early. They will be mapped during clock initialization using of_iomap(). Remove the early mapping. In addition, remove the extraneous zynq_soc.h include from the timer driver.

2012-11-12ARM: zynq: dts: split up device treeJosh Cartwright
The purpose of the created zynq-7000.dtsi file is to describe the hardware common to all Zynq 7000-based boards. Also, get rid of the zynq-ep107 device tree, since it is not hardware anyone can purchase. Add a zc702 dts file based on the zynq-7000.dtsi. Add it to the dts/Makefile so it is built with the 'dtbs' target. Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Acked-by: Michal Simek <michal.simek@xilinx.com>
2012-11-07ARM: zynq: Allow UART1 to be used as DEBUG_LL console.Nick Bowler
The main UART on the Xilinx ZC702 board is UART1, located at address e0001000. Add a Kconfig option to select this device as the low-level debugging port. This allows the really early boot printouts to reach the USB serial adaptor on this board. For consistency's sake, add a choice entry for UART0 even though it is the the default if UART1 is not selected.

2012-11-05ARM: implement debug_ll_io_init()Rob Herring
When using DEBUG_LL, the UART's (or other HW's) registers are mapped into early page tables based on the results of assembly macro addruart. Later, when the page tables are replaced, the same virtual address must remain valid. Historically, this has been ensured by using defines from <mach/iomap.h> in both the implementation of addruart, and the machine's .map_io() function. However, with the move to single zImage, we wish to remove <mach/iomap.h>. To enable this, the macro addruart may be used when constructing the late page tables too; addruart is exposed as a C function debug_ll_addr(), and used to set up the required mapping in debug_ll_io_init(), which may called on an opt-in basis from a machine's .map_io() function. Signed-off-by: Rob Herring <rob.herring@calxeda.com> [swarren: Mask map.virtual with PAGE_MASK. Checked for NULL results from debug_ll_addr (e.g. when selected UART isn't valid).

2012-10-29zynq: remove use of CLKDEV_LOOKUPJosh Cartwright
The Zynq support in mainline does not (yet) make use of any of the generic clk or clk lookup functionality. Remove what is upstream for now, until the out-of-tree implementation is in suitable form for merging. An important side effect of this patch is that it allows the building of a Zynq kernel without running into unresolved symbol problems: drivers/built-in.o: In function `amba_get_enable_pclk': clkdev.c:(.text+0x444): undefined reference to `clk_enable' drivers/built-in.o: In function `amba_remove': clkdev.c:(.text+0x488): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_probe': clkdev.c:(.text+0x540): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_device_add': clkdev.c:(.text+0x77c): undefined reference to `clk_disable' drivers/built-in.o: In function `enable_clock': clkdev.c:(.text+0x29738): undefined reference to `clk_enable' drivers/built-in.o: In function `disable_clock': clkdev.c:(.text+0x29778): undefined reference to `clk_disable' drivers/built-in.o: In function `__pm_clk_remove': clkdev.c:(.text+0x297f8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_suspend': clkdev.c:(.text+0x29bc8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_resume': clkdev.c:(.text+0x29c28): undefined reference to `clk_enable' make[2]: *** [vmlinux] Error 1 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 In addition, eliminate Zynq's "use" of the versatile platform, as it is no longer needed. As Nick Bowler points out: For the record, I think this was introduced by commit 56a34b03ff427 ("ARM: versatile: Make plat-versatile clock optional") which forgot to select PLAT_VERSATILE_CLOCK on Zynq. This is not all that surprising, because the fact that Zynq "uses" PLAT_VERSATILE is secretly hidden in the Makefile. Nevertheless, the only feature from versatile that Zynq needed was the clock support, so this patch should *also* delete the secret use of plat-versatile by removing this line from arch/arm/Makefile: plat-$(CONFIG_ARCH_ZYNQ) += versatile Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Cc: John Linn <john.linn@xilinx.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Tested-by: Michal Simek <michal.simek@xilinx.com>

The i2c core driver will turn the platform device ID to busnum When using platfrom device ID as -1, it means dynamically assigned the busnum. When writing code, we need to make sure the busnum, and call i2c_register_board_info(int busnum, ...) to register device if using -1, we do not know the value of busnum In order to solve this issue, set the platform device ID as a fix number Here using 0 to match the busnum used in i2c_regsiter_board_info() Signed-off-by: Bo Shen <voice.shen@atmel.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Ludovic Desroches <ludovic.desroches@atmel.com>

2012-10-24ARM: at91: fix external interrupt specification in board codeNicolas Ferre
Since the switch to sparse irq, we have to add the NR_IRQS_LEGACY offset to static irq numbers. It has been forgotten on these SPI irq definitions in board code.

2012-10-24ARM: at91: fix external interrupts in non-DT caseNicolas Ferre
Management of external interrupts has changed but the non-DT code has not integrated these changes. Add a mask to pass external irq specification from SoC specific code to the at91_aic_init() function.

2012-10-24ARM: at91: at91sam9g10: fix SOC type detectionIvan Shugov
Newer at91sam9g10 SoC revision can't be detected, so the kernel can't boot with this kind of kernel panic: "AT91: Impossible to detect the SOC type" CPU: ARM926EJ-S [41069265] revision 5 (ARMv5TEJ), cr=00053177 CPU: VIVT data cache, VIVT instruction cache Machine: Atmel AT91SAM9G10-EK Ignoring tag cmdline (using the default kernel command line) bootconsole [earlycon0] enabled Memory policy: ECC disabled, Data cache writeback Kernel panic - not syncing: AT91: Impossible to detect the SOC type [<c00133d4>] (unwind_backtrace+0x0/0xe0) from [<c02366dc>] (panic+0x78/0x1cc) [<c02366dc>] (panic+0x78/0x1cc) from [<c02fa35c>] (at91_map_io+0x90/0xc8) [<c02fa35c>] (at91_map_io+0x90/0xc8) from [<c02f9860>] (paging_init+0x564/0x6d0) [<c02f9860>] (paging_init+0x564/0x6d0) from [<c02f7914>] (setup_arch+0x464/0x704) [<c02f7914>] (setup_arch+0x464/0x704) from [<c02f44f8>] (start_kernel+0x6c/0x2d4) [<c02f44f8>] (start_kernel+0x6c/0x2d4) from [<20008040>] (0x20008040) The reason for this is that the Debug Unit Chip ID Register has changed between Engineering Sample and definitive revision of the SoC. Changing the check of cidr to socid will address the problem. We do not integrate this check to the list just above because we also have to make sure that the extended id is disregarded.
