* ARM: shmobile: r8a7791: Remove legacy codeLaurent Pinchart2014-10-301-338/+0
| | | | | | | | All r8a7791 boards are now used with multiplatform kernels only. We can remove all the unused r8a7791 legacy device and clock registration code. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
* ARM: shmobile: Remove FSF address from copyright headersLaurent Pinchart2014-10-271-4/+0
| | | | | | | | | | The information is already included in the COPYING file in the kernel sources root directory, we don't want to modify all source files when the FSF will move to a new address, and I'm tired of seeing the related checkpatch.pl warnings.

This fix does not have any run-time affect at this time. * ARM: shmobile: r8a7790: add missing 0x0100 for SDCKCR This resolves a problem introduced by 9f13ee6f83c52065 ("ARM: shmobile: r8a7790: add div4 clocks") which was included in v3.11. This fix does not have any run-time affect at this time. * ARM: shmobile: sh73a0: Remove spurious 0x from SCIFB clock name This resolves a problem introduced by a0f7e7496d56ac2d ("ARM: shmobile: sh73a0: add CMT1 clock support for DT") which was included in v3.17-rc1. This fix does not have any run-time affect at this time as the clock in question is used by a SCIF device that is not enabled by default. * tag 'renesas-clock-fixes-for-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: shmobile: r8a7791: add missing 0x0100 for SDCKCR ARM: shmobile: r8a7790: add missing 0x0100 for SDCKCR ARM: shmobile: sh73a0: Remove spurious 0x from SCIFB clock name Signed-off-by: Olof Johansson <olof@lixom.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4bfb358b1d6cdeff8c6a13677f01ed78e9696b98 (ARM: shmobile: Add r8a7791 legacy SDHI clocks) added r8a7791 SDHI clock support. But, it is missing "0x0100: x 1/8" division ratio. This patch fixes hidden bug. It is based on R-Car H2 v0.7, R-Car M2 v0.9.

* ARM: shmobile: r8a7791: Remove legacy clock aliases for DT devicesLaurent Pinchart2014-02-241-1/+0
| | | | | | | | | | 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.

* ARM: shmobile: r8a7791: Wait for status on all MSTP clocksShinya Kuribayashi2014-02-041-30/+38
| | | | | | | | | | | | | | 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.
