rockchip: clk: rk3399: 24MHz is not a power of 2

2017-04-05T02:01:57+00:00

The clock driver for the RK3399 mistakenly used (24 * 2^20) where it
should have used (24 * 10^6) in a few calculations.

This commits fixes this.

rockchip: clk: rk3399: add clocking support for Ethernet

2017-04-05T02:01:57+00:00

The Ethernet driver for the RK3288/3399 GMAC makes sure that the clock
is ungated through a call to clk_set_rate(...). Even though nothing
needs to be done on the RK3399 (the clock gates are open and the clock
is external), we need to implement enough support to at least return
success to enable driver probing.

rockchip: clk: rk3399: fix warnings for unused variables in SPL/non-SPL

2017-04-05T02:01:57+00:00

Due to differences in the code paths for SPL and non-SPL, some static
constant structures remain unused in each build variant. This raises
warnings with recent GCC versions (we currently use GCC-6.3).

The warnings addressed in this commit (by matching #if conditions for
the variable definition with their uses) are:

* for the SPL build:
    drivers/clk/rockchip/clk_rk3399.c:53:29: warning: 'cpll_init_cfg' defined but not used [-Wunused-const-variable=]
     static const struct pll_div cpll_init_cfg = PLL_DIVISORS(CPLL_HZ, 1, 2, 2);
                                 ^~~~~~~~~~~~~
    drivers/clk/rockchip/clk_rk3399.c:52:29: warning: 'gpll_init_cfg' defined but not used [-Wunused-const-variable=]
     static const struct pll_div gpll_init_cfg = PLL_DIVISORS(GPLL_HZ, 2, 2, 1);
                                 ^~~~~~~~~~~~~
* for the non-SPL build:
    drivers/clk/rockchip/clk_rk3399.c:54:29: warning: 'ppll_init_cfg' defined but not used [-Wunused-const-variable=]
     static const struct pll_div ppll_init_cfg = PLL_DIVISORS(PPLL_HZ, 2, 2, 1);
                                 ^~~~~~~~~~~~~

rockchip: clk: rk3188: Allow configuration of the armclk

2017-04-05T02:01:57+00:00

The armclk starts in slow mode (24MHz) on the rk3188, which makes the whole
startup take a lot of time. We therefore want to at least move to the safe
600MHz value we can use with default pmic settings.
This is also the freqency the proprietary sdram-init leaves the cpu at.

For boards that have pmic control later in u-boot, we also add the option
to set the maximum frequency of 1.6GHz, if they so desire.

Merge git://git.denx.de/u-boot-rockchip

2017-03-17T18:15:17+00:00

This includes support for rk3188 from Heiko Stübner and and rk3328 from
Kever Yang.  Also included is SPL support for rk3399 and a fix for
rk3288 to get it booting again (spl_early_init()).

stm32f7: clk: remove usart1 clock enable from board init

2017-03-17T18:15:14+00:00

Before clock driver availability it was required to enable usart1 clock
for serial init but now with clock driver is taking care of usart1 clock.

rockchip: clk: rk3288: limit gpll and cpll init to SPL build

2017-03-16T22:03:44+00:00

The gpll and cpll init values are only used in rk_clk_init in the SPL
and therefore produce compile time warnings in regular uboot builds.
Fix that with an #ifdef.
