2015-08-03ARM: dts: pangolin: Switch led trigger to mmc1Jakob Unterwurzacher
mmc0 and mmc1 have swapped places, mmc0 is the emmc now. Also, let's have better labels.
2015-07-31ARM: sunxi: dts: pangolin: disable 1.2Ghz cpufreqKlaus Goger
disable the 1.2Ghz frequency point so users have to enable it explicity. this should ensure that only boards with installed thermal solutions are used with 1.2Ghz. Note that running on 1.2Ghz will not damage the board as we turn CPU off when overheating. We only want to avoid unexpected shutdowns for users when using the default setup and not mounting the heat sink. Signed-off-by: Klaus Goger <klaus.goger@theobroma-systems.com>

2015-07-30clk: sunxi: Address sun6i PLL1 stability issues.Christoph Muellner
Tests on several Allwinner A31 SoCs showed that PLL1 has problems when using low values for M in combination with high target frequencies. This patch addresses this issue by limiting M, such that it does not divide values higher than 2.6 GHz.

Signed-off-by: Octav Zlatior <octav.zlatior@theobroma-systems.com>
2015-07-30thermal: adds step-wise frequency cappingOctav Zlatior
Frequency capping forces the cooling state to a minimum, defined by the device tree. This forces the frequency to stay below a maximum determined by the operating points as long as we are above a thermal trip point. Signed-off-by: Octav Zlatior <octav.zlatior@theobroma-systems.com>

2015-07-30clk: sunxi: removes pll stability tweaksOctav Zlatior
The pll stability tweaks are no longer necessary, since the cpu clock uses the transition parent while the pll changes the frequency Signed-off-by: Octav Zlatior <octav.zlatior@theobroma-systems.com>
2015-07-30cpufreq: use transition mode during transitionsOctav Zlatior
A call to the clk_use_transition_mode is issued on transition begin. Signed-off-by: Octav Zlatior <octav.zlatior@theobroma-systems.com>
2015-07-30clk: adds support for transition-clock propertyOctav Zlatior
The transition-clock property defines a parent clock to be used by a clock consumer during frequency transitions in variable frequency clocks. It is specified by referencing a clock (must be a parent clock). The clock functions clk_set_transition_parent and clk_get_transition_parent are defined to work with the transition parent in clocks. The clock function clk_use_transition_mode sets the clock parent to the specified transition parent. Signed-off-by: Octav Zlatior <octav.zlatior@theobroma-systems.com>
2015-07-30dts: sunxi: changes operating points for stabilityOctav Zlatior

* operating points for different frequencies with voltages set to optimize power consumption * clock latency and ramp-rate: these values seem to provide enough time for the voltage to adjust before frequency changes Signed-off-by: Octav Zlatior <octav.zlatior@theobroma-systems.com>
2015-07-30Regulator: axp20x: Enable support or set_voltage_time_sel.Christoph Muellner
The cpufreq operating points from the cpufreq-dt driver allows to define the property 'clock-latency' which is intended to be a delay used between changing the voltage and changing the frequency. This patch sets the set_voltage_time_sel function pointer to the default implementation from regulator/core.c. Signed-off-by: Christoph Muellner <christoph.muellner@theobroma-systems.com>

2015-07-30clk: check ->determine/round_rate() return value in clk_calc_new_ratesBoris Brezillon
->determine_rate() and ->round_rate() can return the closest rate to the requested one or an error code. clk_calc_new_rates is assuming these functions can't return a negative value, which leads to a undefined behavior when the clk implementation returns such an error code. Fix this by returning NULL in case ->determine_rate() or ->round_rate() returned an error code.

2015-07-30Clk: Sunxi: Add support for reparenting.Christoph Muellner
This patch adds support for reparenting sunxi factor clocks. The idea is simple: if the DTS provides all possible parents in the correct order, they can be tagged by "clocks-complete" = "ok"; If such a property is found in a sunxi factor clock, then the reparenting uses the indices of the parent list provided in the DTB and the new clock properties parentwidth and parentshift to set the new parent in the clock configuration register.

2015-07-30Clk: Fixed: Registering fixed clocks as clkdev.Christoph Muellner

2015-07-30Clk: sunxi: Fixing sun6i PLL1 factor calculation.Christoph Muellner
