clk: sunxi: Make reset_control_ops const

2016-03-29T23:30:07+00:00

The sunxi_ve_reset_ops, sun9i_mmc_reset_ops, and sunxi_usb_reset_ops structures are never modified. Make them const. Signed-off-by: Philipp Zabel Signed-off-by: Stephen Boyd

clk: sunxi: Remove use of variable length array

2016-03-15T22:15:27+00:00

Using an array allocated on the stack may lead to stack overflows and other problems so let's move the allocation to the heap instead. This silences the following checker warning as well. drivers/clk/sunxi/clk-sun8i-mbus.c:36:29: warning: Variable length array is used Cc: Chen-Yu Tsai Acked-by: Maxime Ripard Signed-off-by: Stephen Boyd

clk: sunxi: Add apb0 gates for H3

2016-02-25T19:30:32+00:00

This patch adds support for APB0 in H3. It seems to be compatible with earlier SOCs. apb0 gates controls R_ block peripherals (R_PIO, R_IR, etc). Since this gates behave just like any Allwinner clock gate, add a generic compatible that can be reused if we don't have any clock to protect.

clk: sunxi: Improve divs_clk error handling and reporting

2016-02-22T03:44:49+00:00

We catch errors in the base clock registration, failure to ioremap and failures in the final of_clk_add_provider() call. Also we unmap the registers when we need to rollback. Signed-off-by: Andre Przywara Signed-off-by: Maxime Ripard

clk: sunxi: improve divider_clk error handling and reporting

2016-02-22T03:44:38+00:00

We now report a failing ioremap, failing output names parsing, failures in table registration and in the final step. Also there was a bug where clk_register_divider_table() would return an ERR_PTR value instead of NULL, which we were checking for. We now implement proper rollback in case of an error.

clk: sunxi: improve mux_clk error handling and reporting

2016-02-22T03:44:09+00:00

We now catch and report a failing ioremap, also a failure in the final step of the clock registration is now handled and reported. Also warnings are turned into errors. Signed-off-by: Andre Przywara Signed-off-by: Maxime Ripard

clk: sunxi: Fix sun8i-a23-apb0-clk divider flags

2016-02-16T08:47:41+00:00

The APB0 clock on A23 is a zero-based divider, not a power-of-two based divider. Note that this patch does not apply cleanly to kernels before 4.5-rc1, which added CLK_OF_DECLARE support to this driver.

clk: sunxi: Remove clk_register_clkdev calls

2016-02-11T19:05:47+00:00

Now that our protection code doesn't use the global name lookup anymore, we can remove the clkdev registrations. Signed-off-by: Maxime Ripard

clk: sunxi: Remove old probe and protection code

2016-02-11T19:05:47+00:00

Now that we don't have any user left for the old registration code, we can remove it. Signed-off-by: Maxime Ripard

clk: sunxi: convert current clocks registration to CLK_OF_DECLARE

2016-02-11T19:05:46+00:00

The current clock registration and protection code has a few drawbacks, the two main ones being that we create a lot of orphans clock in the registration phase, which will be troublesome when we will start being less relaxed about them. The protection code also relies on clkdev, which we don't really use but for this particular case. Fix both at the same time by moving everyone to the CLK_OF_DECLARE that will probe our clock tree in the right and thus avoid orphans, and by protecting directly the clock returned by our registration function.
