2012-02-13mmc: esdhc: set the timeout to the max valueJerry Huang
When accessing the card on some FSL platform boards (e.g p2020, p1010, mpc8536), the following error is reported with the timeout value calculated: mmc0: Got data interrupt 0x00000020 even though no data operation was in progress. mmc0: Got data interrupt 0x00000020 even though no data operation was in progress. So we skip the calculation of timeout and use the max value to fix it.

2012-02-13mmc: esdhc: add PIO mode supportJerry Huang
For some FSL ESDHC controllers (e.g. P2020E, Rev1.0), the SDHC can not work on DMA mode because of the hardware bug, so we set a broken dma flag and use PIO mode.

2012-02-12mmc: esdhc: fix errors when booting kernel on Freescale eSDHC version 2.3Roy Zang
When eSDHC module is enabled on P5020/P3041/P2041/P1010 with eSDHC version 2.3, there is following errors: mmc0: Timeout waiting for hardware interrupt. mmc0: error -110 whilst initialising SD card mmc0: Unexpected interrupt 0x02000000. mmc0: Timeout waiting for hardware interrupt. mmc0: error -110 whilst initialising SD card mmc0: Unexpected interrupt 0x02000000. It is because eSDHC controller has different bit setting for PROCTL register at 0x28 comparing SD specification. This patch sets DMAS bits correctly for byte operation and does not change the default value of other field of PROCTL register. For other FSL chips, such as MPC8536/P2020, PROCTL[DMAS] bits are reserved and even if they are set to wrong bits, it will not take effective.

MISC_DEVICES option alone does not select any kernel code and can cause dependency build warnings, such as: warning: (KS8851 && AX88796_93CX6 && RTL8180 && RTL8187 && ADM8211 && RT2400PCI && RT2500PCI && RT61PCI && RT2800PCI && R8187SE) selects EEPROM_93CX6 which has unmet direct dependencies (MISC_DEVICES) As the current drivers/misc/Kconfig stands, it is only possible to select the drivers below if MISC_DEVICES option is selected: source "drivers/misc/c2port/Kconfig" source "drivers/misc/eeprom/Kconfig" source "drivers/misc/cb710/Kconfig" source "drivers/misc/iwmc3200top/Kconfig" source "drivers/misc/ti-st/Kconfig" source "drivers/misc/lis3lv02d/Kconfig" source "drivers/misc/carma/Kconfig" source "drivers/misc/altera-stapl/Kconfig" So remove MISC_DEVICES option so that nothing is dependant on it.

clock management changes for i.MX Another simple series related to clock management, this time only for imx. * tag 'clk' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: mxs: select HAVE_CLK_PREPARE for clock clk: add config option HAVE_CLK_PREPARE into Kconfig ASoC: mxs-saif: convert to clk_prepare/clk_unprepare video: mxsfb: convert to clk_prepare/clk_unprepare serial: mxs-auart: convert to clk_prepare/clk_unprepare net: flexcan: convert to clk_prepare/clk_unprepare mtd: gpmi-lib: convert to clk_prepare/clk_unprepare mmc: mxs-mmc: convert to clk_prepare/clk_unprepare dma: mxs-dma: convert to clk_prepare/clk_unprepare net: fec: add clk_prepare/clk_unprepare ARM: mxs: convert platform code to clk_prepare/clk_unprepare clk: add helper functions clk_prepare_enable and clk_disable_unprepare Fix up trivial conflicts in drivers/net/ethernet/freescale/fec.c due to commit 0ebafefcaa7a ("net: fec: add clk_prepare/clk_unprepare") clashing trivially with commit e163cc97f9ac ("net/fec: fix the .remove code").
