2014-05-11ARM: shmobile: r8a7791: Switch to new style CMT deviceLaurent Pinchart
The CMT (Compare Match Timer) driver implements a new style of platform data that handles the timer as a single device with multiple channel. Switch from the old-style platform data to the new-style platform data.

2014-04-14ARM: shmobile: r8a7791: Fix the I2C clocks parents in legacy codeLaurent Pinchart
All I2C clocks derive from the HP clock, not from the P clock. Fix them.

2014-03-13ARM: shmobile: r8a7791: Fix SCIFA3-5 clocksGeert Uytterhoeven
The MSTP clocks for SCIFA3-5 are MSTP1106-1108, not MSTP1105-1107 Also reinsert them at the correct position to preserve sort order. Signed-off-by: Geert Uytterhoeven <geert+renesas@linux-m68k.org> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2014-02-24ARM: shmobile: r8a7791: Remove legacy clock aliases for DT devicesLaurent Pinchart
Now that the r8a7791 DT platforms use the common clock framework, there's no need to manually create clock aliases for devices instantiated through DT, as those devices will reference their clocks directly in the device tree. Remove those aliases. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2014-02-04ARM: shmobile: r8a7791: Wait for status on all MSTP clocksShinya Kuribayashi
When enabling a module clock by clearing its bit in the MSTP control register, the CPG requires waiting for the status register to signal that the clock has started. Failure to do so will result in returning from the clk_enable() call with the clock potentially still disabled, leading to various race conditions and difficult to debug errors. Enable status wait for all MSTP clocks on the r8a7791.
