2013-12-31ARM: imx: improve status check of clock gateAnson Huang1-1/+1
For ccm clock gate, both 2b'11 and 2b'01 should be treated as clock enabled, see below description in CCM, whenver CPU trys to check clock gate's status, system will be in run mode. 2b'00: clock is off during all modes; 2b'01: clock is on in run mode, but off in wait and stop mode; 2b'10: Not applicable; 2b'11: clock is on during all modes, except stop mode.

2013-04-01ARM: mach-imx: clk-gate2: Include "clk.h"Fabio Estevam1-0/+1
Fix the following sparse warning: arch/arm/mach-imx/clk-gate2.c:86:12: warning: symbol 'clk_register_gate2' was not declared. Should it be static? Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2012-11-16ARM i.MX: fix error-valued pointer dereference in clk_register_gate2()Wei Yongjun1-1/+1
The error-valued pointer clk is used for the arg of kfree, it should be kfree(gate) if clk_register() return ERR_PTR(). dpatch engine is used to auto generate this patch.

2012-05-02ARM i.MX: Add common clock support for 2bit gateSascha Hauer1-0/+118
This gate consists of two bits: 0b00: clk disabled 0b01: clk enabled in run mode and disabled in sleep mode 0b11: clk enabled Currently only disabled and enabled are supported. As it's unlikely that we find something like this in another SoC create a i.MX specific clk helper for this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
