clk: qcom: select GDSC for msm8996 gcc and mmcc

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

commit 6d91f2c0141330b919ae4d13395f38c341469564 upstream.

This patch selects QCOM_GDSC Kconfig for msm8996 GCC and MMCC clock
controllers, as these provide some of the gdscs on the SOC.

Also selecting this config will make it align with other drivers which
do the same.

clk: gcc-msm8996: Fix pcie 2 pipe register offset

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

commit ce61966c05f276294b6be04d1765ad0d827ddefd upstream.

This patch corrects the register offset for pcie2 pipe clock.
Offset according to datasheet is 0x6e018 instead of 0x6e108.

clk: qcom: add EBI2 clocks to the MSM8660 GCC

2016-07-02T01:12:45+00:00

This adds the EBI2 2X and EBI2 clocks to the MSM8660/APQ8060
GCC. This is necessary to enable clocking of the external bus
interface so that peripherals on it can be mounted. These two
clocks are simple gated branch clocks.

In the vendor tree clock-8x60, these clocks have some kind of
dependency, the EBI2 clock has .depends = &ebi2_2x_clk.c,
what this means is undocumented, it doesn't seem like there
is a parent/child relationship, so the solution I chose was to
just have the EBI2 driver get and enable both clocks.

clk: qcom: Remove gcc_aggre1_pnoc_ahb_clk from msm8996

2016-06-28T23:36:22+00:00

This clk is critical to operation of the SoC and should never be
turned off. Furthermore, there are no consumers of this clk so
let's just delete it so things like eMMC work.

clk: qcom: mmcc-8996: Remove clocks that should be controlled by RPM

2016-05-12T21:48:28+00:00

The branch clocks MMSS_MMAGIC_AXI_CLK and MMAGIC_BIMC_AXI_CLK are
controlled by RPM when the APPs processor enable or disable the
RPM_MMAXI_CLK.

During the boot sequence, someone can enable the RPM_MMAXI_CLK, resulting
in register status bits showing that these clocks are enabled, our
clock driver may look at the enabled status of these clocks and try to
disable them since it thinks they are unused.

Don't make the clock driver touch these clocks.

clk: qcom: msm8916: Fix crypto clock flags

2016-05-06T18:04:26+00:00

This patch adds the CLK_SET_RATE_PARENT flag for the crypto core and
ahb blocks.  Without this flag, clk_set_rate can fail for certain
frequency requests.

clk: qcom: ipq4019: add some fixed clocks for ddrppl and fepll

2016-03-29T23:31:16+00:00

Drivers for these don't exist yet so we will add them as fixed clocks
so we don't BUG() if we change clocks that reference these clocks.

clk: qcom: ipq4019: switch remaining defines to enums

When this was added not all the remaining defines were switched over to
use enums, so let's complete that process here
