2014-02-26clk:at91: Fix memory leak in of_at91_clk_master_setup()Masanari Iida1-1/+1

2014-02-26clk: axi-clkgen: Add support for v2Lars-Peter Clausen2-44/+270
This patch adds support for the new v2 version of the axi-clkgen core. Unfortunately the method of accessing the registers is quite different on v2, while the content still stays largely the same. So the patch adds a small abstraction layer which implements the specific read and write functions for v1 and v2 in callback functions. Signed-off-by: Lars-Peter Clausen <[email protected]>

2014-02-26clk: nomadik: fix multiplatform problemLinus Walleij1-0/+3
The Nomadik debugfs screws up multiplatform boots if debugfs is enabled on the multiplatform image, since it's a simple initcall that is unconditionally executed and reads from certain memory locations. Fix this by checking that the driver has been properly initialized, so a base offset to the Nomadik SRC controller exists, before proceeding to register debugfs files.

2014-02-21usb: chipidea: need to mask when writting endptflush and endptprimeMatthieu CASTET1-2/+2
ENDPTFLUSH and ENDPTPRIME registers are set by software and clear by hardware. There is a bit for each endpoint. When we are setting a bit for an endpoint we should make sure we do not touch other endpoint bit. There is a race condition if the hardware clear the bit between the read and the write in hw_write.
