2014-05-14ARM: shmobile: lager: Enable SCIF0 and SCIF1 serial ports in DTLaurent Pinchart
SCIF0 and SCIF1 are used as debug serial ports. Enable them and configure pinmuxing appropriately. We can now remove the clkdev registration hack for SCIF devices from the Lager reference board file.

2014-05-11ARM: shmobile: r8a7790: 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: Add Lager clock workarounds for SDHI and MMCIFMagnus Damm
Add MMCIF1, SDHI0 and SDHI2 to the clock workaround list for Lager multiplatform. Without these additional lines wakeup from Suspend-to-RAM never happens. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2014-04-14ARM: shmobile: lager-reference: Work around core clock issuesSimon Horman
Due to issues with runtime PM clock management, clocks not explicitly managed by their drivers may not be enabled at all, or be inadvertently disabled by the clk_disable_unused() late initcall. Until this is fixed, add a temporary workaround, calling shmobile_clk_workaround() with enable == true. For now this enables the clocks for: ether, msiof1, qspi_mod, and thermal. More clocks can be added if needed. Based on work for the koelsch board by Geert Uytterhoeven.

Convert the Lager DT reference code to use the newly introduced function shmobile_clk_workaround(). Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2014-02-18ARM: shmobile: Remove Lager DT reference legacy clock bitsMagnus Damm
Lager DT reference is these days built for multiplatform only which means that CCF comes with the package. Remove unused legacy code ifdefs to clean up the code.

2014-02-04ARM: shmobile: lager: fix error return code check from clk_get()Ben Dooks
The lager_add_standard_devices() function calls clk_get() but then fails to check that it returns an error pointer instead of NULL on failure. This was added by 4a606af2 ("ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMT") patch in Simon Horman's renesas-boards2-for-v3.14 tag. The issue is not serious as it does not cause a crash and seems to not be actually causing any issues now the other clock bugs have been fixed.

2013-12-19ARM: shmobile: Let Lager multiplatform boot with Lager DTBLaurent Pinchart
Let the multiplatform Lager support boot with the legacy DTS for Lager as well as the Lager reference DTS. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-12-19ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMTLaurent Pinchart
Now that the common clock framework is supported, the clock lookup entries in clock-r8a7790.c are not registered anymore. Devices must instead reference their clocks in the device tree. However, SCIF and CMT devices are still instantiated through platform code, and thus need a clock lookup entry. Retrieve the SCIF and CMT clock entries by name and register clkdevs for the corresponding devices. This will be removed when the SCIF and CMT devices will be instantiated from the device tree.

2013-12-19ARM: shmobile: lager-reference: Enable multiplaform kernel supportLaurent Pinchart
Enable multiplaform ARM architecture support for the Lager reference board. Common clock framework initialization will be handled by the rcar_gen2_init_timer() call, we just need to remove the legacy clock code initialization.

2013-12-10ARM: shmobile: Use ->init_late() on LagerMagnus Damm
Hook in shmobile_init_late() on Lager V2. This enables some PM related things like CPUIdle and Suspend-to-RAM. With this patch applied it is possible to use Suspend-to-RAM: # echo enabled > /sys/class/tty/ttySC6/power/wakeup # echo mem > /sys/power/state (wake by sending a character on the serial console) Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2013-09-30ARM: shmobile: Add r8a7790 SMP support using APMU codeMagnus Damm
Add r8a7790 SMP support using the shared APMU code. To enable SMP the r8a7790 specific DTS needs to be updated to include CPU cores, and this is happening in a separate patch. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2013-07-17ARM: shmobile: lager: Add DT referenceSimon Horman
This is sufficient to allow boot of the Lager board with a console without boards-lager.c compiled into the kernel. This is an example of a minimal but still useful initialisation of the board using DT as much as possible. As such it is the same as the boot of Lager that can be achieved without a board file. The intention of adding this file is to facilitate further work to allow board specific devices to be initialised via DT.
