rockchip: video: vop: Fix rk_display_init() return error

It's caused by the difference of clk_set_rate function implement between
rk3288 andd rk3399.

clk_set_rate() of rk3288 return 0 in normal condition.
clk_set_rate() of rk3399 return input parameter in normal condition.

So check clk_set_rate's return value by IS_ERR_VALUE.

Philipp Tomsich [Thu, 20 Apr 2017 20:05:52 +0000 (22:05 +0200)]
rockchip: spi: rewrite rkspi_set_clk for a more conservative baudrate setting

The baudrate in rkspi was calculated by using an integer division
(which implicitly discarded any fractional result), then rounding to
an even number and finally clamping to 0xfffe using a bitwise AND
operator.  This introduced two issues:
1) for very small baudrates (overflowing the 0xfffe range), the
   bitwise-AND generates rather random-looking (wildly varying)
   actual output bitrates
2) for higher baudrates, the calculation tends to 'err towards a
   higher baudrate' with the actual error increasing as the dividers
   become very small. E.g., with a 99MHz input clock, a request
   for a 20MBit baudrate (99/20 = 4.95), a 24.75 MBit would be use
   (which amounts to a 23.75% error)... for a 34 MBit request this
   would be an actual outbout of 49.5 Mbit (i.e. a 45% error).

This change rewrites the divider selection (i.e. baudrate calculation)
by making sure that
a) for the normal case: the largest representable baudrate below the
   requested rate will be chosen;
b) for the denormal case (i.e. when the divider can no longer be
   represented), the lowest representable baudrate is chosen.

Even though the denormal case (b) may be of little concern in real
world applications (even with a 198MHz input clock, this will only
happen at below approx. 3kHz/3kBit), our board-verification team kept
complaining.

rockchip: spi: rk_spi: dynamically select an module input rate

The original clock/bitrate selection code for the rk_spi driver was a
bit limited, as it always selected a 99MHz input clock rate (which
would allow for a maximum bitrate of 49.5MBit/s), but returned -EINVAL
if a bitrate higher than 48MHz was requested.

To give us better control over the bitrate (i.e. add more operating
points, especially at "higher" bitrate---such as above 9MBit/s), we
try to choose 4x the maximum frequency (clamped to 50MBit) from the
DTS instead of 99MHz... for most use-cases this will yield a frequency
of 198MHz, but is flexible to go beyond this in future configurations.

This also rewrites the check to allow frequencies of up to half the
SPI module rate as bitrates and then clamps to whatever the DTS allows
as a maximum (board-specific) frequency and does away with the -EINVAL
when trying to select a bitrate (for cases that exceeded the hard
limit) and instead consistently clamps to the lower of the hard limit,
the soft limit for the SPI bus (from the DTS) or the soft limit for
the SPI slave device.

rockchip: clk: rk3399: fix off-by one during rate calculation in i2c/spi_set_rate

For the RK3399, i2c_set_rate (and by extension: our spi_set_rate,
which had been mindlessly following the template of the i2c_set_rate
implementation) miscalculates the rate returned due to a off-by-one
error resulting from the following sequence of events:
  1. calculates 'src_div := src_freq / target_freq'
  2. stores 'src_div - 1' into the register (the actual divider applied
     in hardware is biased by adding 1)
  3. returns the result of the DIV_RATE(src_freq, src_div) macro, which
     expects the (decremented) divider from the hardware-register and
     implictly adds 1 (i.e. 'DIV_RATE(freq, div) := freq / (div + 1)')

This can be observed with the SPI driver, which sets a rate of 99MHz
based on the GPLL frequency of 594MHz: the hardware generates a clock
of 99MHz (src_div is 6, the bitfield in the register correctly reads 5),
but reports a frequency of 84MHz (594 / 7) on return.

To fix, we have two options:
 * either we bias (i.e. "DIV_RATE(GPLL, src_div - 1)"), which doesn't
   make for a particularily nice read
 * we simply call the i2c/spi_get_rate function (introducing additional
   overhead for the additional register-read), which reads the divider
   from the register and then passes it through the DIV_RATE macro

Given that this code is not time-critical, the more readable solution
(i.e. calling the appropriate get_rate function) is implemented in this
change.

the beginning of board_early_init_f.
Instead of doing that, let's provide a generic call to debug_uart_init right
before the call to board_init_f if debug uart is enabled for boards without
stack in SRAM.
On the other hand, boards with stack in SRAM can call earlier (right before
