0a7eec7f59 clk: tegra124: init table updates
Ensure some clocks critical for system operation are always. Also enable csite
for JTAG debugging and set the tsensor and soc_therm clock frequencies for the
upcoming soctherm driver.

cb44cc2f48 clk: tegra: Add SATA clocks to Tegra124 initialization table
This adds two clocks, SATA and SATA_OOB, to the Tegra124 clock initialization
table. The clocks are needed for working SATA support.

167d5366c4 clk: tegra: fix vi_sensor clocks on Tegra124
vi_sensor and vi_sensor2 have a wrong hw clkid on Tegra124. Fix this by
correcting the hw clkid for Tegra124 and creating the Tegra114 vi_sensor clock
from its own data. Tegra124 was also using the wrong internal clock id.

5c992afcf8 clk: tegra: Fix xusb_hs_src clock hierarchy
Currently the Tegra1x4 clock init code hard-codes the mux setting
for xusb_hs_src and treats it as a fixed-factor clock.  It is,
however, a mux which can be parented by either xusb_ss_src/2 or
pll_u_60M.  Add the fixed-factor clock xusb_ss_div2 and put an
entry in periph_clks[] for the xusb_hs_src mux.

9ba7170570 clk: tegra: remove non-existent clocks
The Tegra124 clock driver currently provides 3 clocks that don't actually
exist; 2 for NAND and one for UART5/UARTE. Delete these.

20e7c323ab clk: tegra: fix sdmmc clks on Tegra1x4
The sdmmc clocks on Tegra114 and Tegra124 are 3-bit wide muxes with
6 parents.  Add support for tegra_clk_sdmmc*_8 and switch Tegra114
and Tegra124 to use these clocks instead.

2ec35fd503 clk: tegra: Fix PLLP rate table
This table had settings for 216MHz, but PLLP is (and is supposed to be)
configured at 408MHz.  If that table is used and PLLP_BASE_OVRRIDE is
not set, the kernel will panic in clk_pll_recalc_rate().

6d5b988e7d clk: tegra: implement a reset driver
The Tegra CAR module implements both a clock and reset controller. So
far, the driver exposes the clock feature via the common clock API and
the reset feature using a custom API. This patch adds an implementation
of the common reset framework API (include/linux/reset*.h). The legacy
reset implementation will be removed once all drivers have been
converted.

Hook the functions for CPU hotplug support. After the CPU is hot
unplugged, the flow controller will handle to clock gate the CPU clock.
But still need to implement an empty function to avoid warning message.
