2013-02-19ARM: shmobile: r8a7779: Correct TMU clock support againSimon Horman
After discussion on the linux-sh mailing list and reference to the hardware documentation it appears that 'TMU00', 'TMU01' and 'TMU02' use a common clock. The sh_tmu.1 portion of this change resolves a regression introduced in 58079fa7d54a0929d304054ee759187a2ccd3cdf (ARM: shmobile: r8a7779: Correct TMU clock support) and fixes a regression introduced by that patch. That patch is queued up for v3.9. ... hub 4-0:1.0: USB hub found hub 4-0:1.0: 2 ports detected INFO: rcu_sched self-detected stall on CPUINFO: rcu_sched detected stalls on +CPUs/tasks: { 1} (detected by 2, t=279640 jiffies, g=4294967052, c=4294967051, +q=38) Task dump for CPU 1: swapper/0 R running 0 1 0 0x00000002 [<c02b8f5c>] (__schedule+0x1b0/0x4c0) from [<c013c590>] (__loop_delay+0x4/0xc) { 1} (t=279640 jiffies g=4294967052 c=4294967052 q=37) [<c000ef9c>] (unwind_backtrace+0x0/0xf8) from [<c0068488>] +(rcu_check_callbacks+0x218/0x6b8) [<c0068488>] (rcu_check_callbacks+0x218/0x6b8) from [<c0026774>] +(update_process_times+0x38/0x4c) [<c0026774>] (update_process_times+0x38/0x4c) from [<c00569e0>] +(tick_nohz_handler+0xb4/0x11c) [<c00569e0>] (tick_nohz_handler+0xb4/0x11c) from [<c000e518>] +(twd_handler+0x34/0x44) [<c000e518>] (twd_handler+0x34/0x44) from [<c0063484>] +(handle_percpu_devid_irq+0x68/0x80) [<c0063484>] (handle_percpu_devid_irq+0x68/0x80) from [<c005febc>] +(generic_handle_irq+0x20/0x30) [<c005febc>] (generic_handle_irq+0x20/0x30) from [<c000a5ec>] +(handle_IRQ+0x40/0x90) [<c000a5ec>] (handle_IRQ+0x40/0x90) from [<c000934c>] (gic_handle_irq+0x2c/0x5c) [<c000934c>] (gic_handle_irq+0x2c/0x5c) from [<c0009a40>] (__irq_svc+0x40/0x50) Exception stack(0xef03ddf8 to 0xef03de40) dde0: 000001c1 ffffffff de00: 000001d8 01bf01bf ef35ec40 ef35e800 ef35ec6c 0000002b ef35ec68 c013c560 de20: c0392994 60000113 00000000 ef03de40 c01a5d40 c013c590 20000113 ffffffff [<c0009a40>] (__irq_svc+0x40/0x50) from [<c013c590>] (__loop_delay+0x4/0xc) Cc: Denis Oliver Kropp <dok@directfb.org> Cc: Magnus Damm <damm@opensource.se> Cc: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Cc: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-02-05ARM: shmobile: r8a7779: Correct TMU clock supportSimon Horman
During code review it was noticed that the clock value for TMU01 was incorrect and the value for TMU02 was missing. For reference: As of 3.8-rc6 there are no in-tree consumes of these clocks.

2012-01-09ARM: mach-shmobile: r8a7779 and Marzen base support V2Magnus Damm
Initial support for the r8a7779 SoC and the Marzen board (V2). Only SCIF ports and the TMU are supported at this point. To keep things simple only entity-mapped virt-to-phys mappings are supported. This forces drivers and other SoC glue code to make use of ioremap(). We cannot support early serial console due to virtual address space collisions with the ARM kernel.
