2017-10-27spi: ich: Lock down controller settings if requiredBin Meng2-0/+23
Some Intel FSP (like Braswell) does SPI lock-down during the call to fsp_notify(INIT_PHASE_BOOT). But before SPI lock-down is done, it's bootloader's responsibility to configure the SPI controller's opcode registers properly otherwise SPI controller driver doesn't know how to communicate with the SPI flash device. Rather than passively doing the opcode configuration, let's add a simple DTS property "intel,spi-lock-down" and let the driver call the opcode configuration function if required by such FSP.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada2-4/+4
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err().

2017-08-24x86: ich-spi: Don't read cached lock statusBin Meng2-8/+23
At present the ICH SPI controller driver reads the controller lock status from its register in the probe routine and saves the lock status to a member of priv. Later the driver uses the cached status from priv to judge whether the controller setting is locked and do different setup. But such logic is only valid when there is only the SPI controller driver that touches the SPI hardware. In fact the lock status change can be trigged outside the driver, eg: during the fsp_notify() call when Intel FSP is used. This changes the driver to read the lock status every time when an SPI transfer is initiated instead of reading the cached one.

Note that the assumption that GPLL will be clocked at 594MHz is not true for the RK3368, but this will not lead to incorrect functioning (just to a lower-than-expected SPI operating frequency): this has been documented in the driver, so it doesn't cause any headaches when someone next needs to touch the clock code of this driver.

2017-05-10rockchip: spi: rewrite rkspi_set_clk for a more conservative baudrate settingPhilipp Tomsich1-3/+22
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.

2017-05-10rockchip: spi: rk_spi: dynamically select an module input ratePhilipp Tomsich2-8/+37
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. This replaces "rockchip: spi: rk_spi: select 198MHz input to the SPI module for the RK3399" "rockchip: spi: rk_spi: improve clocking code for the RK3399" from earlier versions of this series.

2017-04-04dm: core: Add flags parameter to device_remove()Stefan Roese1-2/+2
This patch adds the flags parameter to device_remove() and changes all calls to this function to provide the default value of DM_REMOVE_NORMAL for "normal" device removal. This is in preparation for the driver specific pre-OS (e.g. DMA cancelling) remove support.
