clk: bcm2835: Avoid overwriting the div info when disabling a pll_div clk

2017-01-09T07:21:47+00:00

commit 68af4fa8f39b542a6cde7ac19518d88e9b3099dc upstream. bcm2835_pll_divider_off() is resetting the divider field in the A2W reg to zero when disabling the clock. Make sure we preserve this value by reading the previous a2w_reg value first and ORing the result with A2W_PLL_CHANNEL_DISABLE.

clk: bcm2835: Skip PLLC clocks when deciding on a new clock parent

2016-10-31T11:02:12+00:00

commit 67615c588a059b731df9d019edc3c561d8006ec9 upstream. If the firmware had set up a clock to source from PLLC, go along with it. But if we're looking for a new parent, we don't want to switch it to PLLC because the firmware will force PLLC (and thus the AXI bus clock) to different frequencies during over-temp/under-voltage, without notification to Linux. On my system, this moves the Linux-enabled HDMI state machine and DSI1 escape clock over to plld_per from pllc_per. EMMC still ends up on pllc_per, because the firmware had set it up to use that.

clk: bcm: iproc: Migrate to clk_hw based registration and OF APIs

2016-06-30T19:26:45+00:00

Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs.

clk: iproc: fix missing include of clk-iproc.h

2016-06-21T00:44:52+00:00

Fix the implicit declaration of iproc_armpll_setup() by including clk-iproc.h which defines it. Fixes the warning: drivers/clk/bcm/clk-iproc-armpll.c:242:13: warning: symbol 'iproc_armpll_setup' was not declared. Should it be static?

clk: bcm/kona: Do not use sizeof on pointer type

2016-05-06T18:06:44+00:00

When sizeof is applied to a pointer typed expression, it gives the size of the pointer. So, here do not use sizeof on pointer type. Also, silent checkpatch.pl by using kmalloc_array over kmalloc. Note that this has no effect on runtime because 'parent_names' is a pointer to a pointer. Problem found using Coccinelle. Signed-off-by: Vaishali Thakkar Signed-off-by: Stephen Boyd

clk: bcm2835: Fix PLL poweron

2016-04-20T01:56:17+00:00

In poweroff, we set the reset bit and the power down bit, but only managed to unset the reset bit for poweron. This meant that if HDMI did -EPROBE_DEFER after it had grabbed its clocks, we'd power down the PLLH (that had been on at boot time) and never recover.
