From 8626cb8021d92603cb6a305fb686510a8d14d6bd Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Thu, 8 Oct 2015 11:31:47 +0530 Subject: ARM: k2e/l: Apply WA for selecting PA clock source On keystone2 Lamarr and Edison platforms, the PA clocksource mux in PLL REG1, can be changed only after enabling its clock domain. So selecting the output of PASS PLL as input to PA only after enabling the clockdomain. This is as per the debug done by "Vitaly Andrianov " and based on the previous work done by "Hao Zhang " Fixes: d634a0775bcf ("ARM: keystone2: Cleanup PLL init code") Reported-by: Vitaly Andrianov Tested-by: Vitaly Andrianov Signed-off-by: Lokesh Vutla --- arch/arm/mach-keystone/include/mach/clock.h | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/arm/mach-keystone/include/mach/clock.h') diff --git a/arch/arm/mach-keystone/include/mach/clock.h b/arch/arm/mach-keystone/include/mach/clock.h index ddc5f8e..7e51702 100644 --- a/arch/arm/mach-keystone/include/mach/clock.h +++ b/arch/arm/mach-keystone/include/mach/clock.h @@ -118,6 +118,7 @@ unsigned long clk_round_rate(unsigned int clk, unsigned long hz); int clk_set_rate(unsigned int clk, unsigned long hz); int get_max_dev_speed(void); int get_max_arm_speed(void); +void pll_pa_clk_sel(void); #endif #endif -- cgit v1.1
