Anson Huang	b4e844f019	ARM: imx: improve status check of clock gate ... 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.

Fabio Estevam	d7b8c030f6	ARM: mach-imx: clk-gate2: Include "clk.h" ... Fix the following sparse warning: arch/arm/mach-imx/clk-gate2.c:86:12: warning: symbol 'clk_register_gate2' was not declared.

Wei Yongjun	ecf026dc34	ARM i.MX: fix error-valued pointer dereference in clk_register_gate2() ... 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.

Sascha Hauer	b75c015143	ARM i.MX: Add common clock support for 2bit gate ... 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>	2012-05-02 12:08:13 +02:00
