| * mfd: omap-usb-host: Get clocks based on hardware revisionRoger Quadros2014-03-131-4/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all revisions have all the clocks so get the necessary clocks based on hardware revision. This should avoid un-necessary clk_get failure messages that were observed earlier. Also remove the dummy USB host clocks from the OMAP3 clock data. These are no longer expected by the driver.

| * | clk: shmobile: fix setting paretn clock rateBen Dooks2014-04-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the driver needs to change a clock rate, then it must be propogated through the MSTP clock to the parent clock (such as shdi0 -> sd0). Without this we cannot up-rate default clocks which are really slow (such as the mmcif1 which defaults to 12MHz where it could be running at 97MHz) Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clock generator for rcar-gen2 has the lb, sdh, sd0 and sd1 clocks parented to pll1_div2 where the hardware diagram shows these to be directly fed from pll1. This fixes the initial rate for sdh0 clock to be 97.5MHz instead of the reported 48MHz where the manual says the default register values are for 97.5MHz.

This led to have the dependencies between the clocks not respected: children clocks could be initialized before their parent clocks. Instead of forcing each platform to manage its own initialization order, this patch adds this work inside the framework itself. Using the data of the device tree the of_clk_init function now delayed the initialization of a clock provider if its parent provider was not ready yet.

| | * | clk: sunxi: Add support for USB clock-register reset bitsHans de Goede2014-02-181-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usb-clk register is special in that it not only contains clk gate bits, but also has a few reset bits. This commit adds support for this by allowing gates type sunxi clks to also register a reset controller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Divs clocks consist of a parent factor clock with multiple outputs, and seperate clocks for each output.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sunxi clock drivers use dt node name as clock name, but clock nodes should be named clk@X, so the names would be the same. Let the drivers read clock names from dt clock-output-names property.

Similarly to Armada 370 and XP, the Core Divider clocks of the 380 have gate capabilities. The only difference is the register layout.
