From: Martin Sperl <kernel@xxxxxxxxxxxxxxxx> The clk-bcm2835 driver right now relies on BCM2835_CLOCK_COUNT defined in include/dt-binding/clocks/bcm2835.h With every new clock introduced this value needs to increase, which is not what should happen for bindings. So we reorganize the driver so that it is no longer necessary to define BCM2835_CLOCK_COUNT. Also the driver calculates fractional clock dividers correctly, but it does not enable the bit to enable support in the register. As a minimal extension we now can also define higher order MASH support when defining the clocks. There is also an issue when the clock divider is < 2 - in that case no clock-outputis generate. The clamping code has been enhanced to handle this as well. Similarly there is also the clamping of the highest divider now limited to the highest possible integer divider instead of the highest possible fractional diviver. Finally we add all the 23 different HW clocks that have not been configured in the driver. Changelog: V1 -> V2: split the asoc/sound patches from the clock patches enable frac/mash support V2 -> V3: clamp clock divider to be >= 2 clamp max clock divider to be integer (not fractional) added additional limit checks for divider selection allowing fallback to lower mash levels. use a newer probing mechanism based on a single array Martin Sperl (6): clk: bcm2835: the minimum clock divider is 2 clk: bcm2835: clamp clock divider to highest integer only clk: bcm2835: enable fractional and mash support clk: bcm2835: remove use of BCM2835_CLOCK_COUNT in driver clk: bcm2835: enable management of PCM clock clk: bcm2835: add missing 22 HW-clocks. drivers/clk/bcm/clk-bcm2835.c | 550 +++++++++++++++++++++++++++++------ include/dt-bindings/clock/bcm2835.h | 25 +- 2 files changed, 490 insertions(+), 85 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
