2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation.

2016-11-17rockchip/rk3399: Change PLL configuration to match Linux kernelJulius Werner
The Kevin project has been too smooth and boring for our tastes in the last last few weeks, so we've decided to stir the pot a little bit and reshuffle all our PLL settings at the last minute. The new settings match exactly what the Linux kernel expects on boot, so it doesn't need to reinitialize anything and risk a glitch. Naturally, changing PLL rates will affect child clocks, so this patch changes vop_aclk (192MHz -> 200MHz, 400MHz in the kernel), pmu_pclk (99MHz -> 96.57MHz) and i2c0_src (198MHz -> 338MHz, leading to an effective I2C0 change 399193Hz -> 398584Hz). BRANCH=gru BUG=chrome-os-partner:59139 TEST=Booted Kevin, sanity checking display and beep. Instrumented rockchip_rk3399_pll_set_params() in the kernel and confirmed that GPLL, PPLL and CPLL do not get reinitialized anymore (with additional kernel patch to ignore frac divider when it's not used). Also confirmed that /sys/kernel/debug/clk_summary now shows pclk_pmu_src 96571429 because the kernel doesn't even bother to reinitialize the divisor.

2016-10-06rockchip: spi: Add support for 16-bit APB readsSimon Glass
With a SPI clock above about 24MHz the APB cannot keep up when doing individual byte transfers. Adjust the driver to use 16-bit reads when it can, to remove this bottleneck. Any transaction which involves writing bytes still uses 8-bit transfers, to simplify the code. These are the transfers that are not time-critical since they tend to be small. The case that really matters is reading from SPI flash. In general we can use 16-bit reads anytime we are transferring an even number of bytes. If the code detects an odd number of bytes, it tries to perform the operation in two steps: once in 16-bit mode with an even number of bytes, and once in 8-bit mode for the final byte. This allow us to use 16-bit reads even if asked to transfer (for example) 0xf423 bytes. The limit on in_now and out_now is adjusted to 0xfffe to avoid an extra transfer when transferring ~>=64KB. CQ-DEPEND=CL:383232 BUG=chrome-os-partner:56556 BRANCH=none TEST=boot on gru and see that things still work correctly. I tested (with extra debugging) that the 16-bit case is being picked when it should be.

2016-08-11rockchip/rk3399: Add code to neuter Type-C PHY for firmware USBJulius Werner
The Rockchip RK3399 integrates a USB Type-C PHY in charge of things like SuperSpeed line muxing for rotated cable orientations in the SoC. While fancy, this is very complicated and we don't want to implement support for the whole thing in firmware. The USB Type-C standard has intentionally been designed in a way that the USB 2.0 (HighSpeed) lines always "just work" in any orientation (by just shorting different pins in the connector together) so that simple use cases like ours can get basic USB functionality without much hassle. However, a semi-configured Type-C PHY can confuse USB 3.0 capable devices into thinking we're actually supporting SuperSpeed, and fail at that rather than establishing a reliable HighSpeed connection. This patch sets enough bits in the Type-C PHY to electrically isolate the SuperSpeed lines from the connector so that the connected device isn't going to get any fancy ideas and reliably falls back to USB 2.0. Also clean up the rest of the USB code while we're at it: avoid writing a few bits that are already in the right state from their reset values anyway, or reading values whose content we already know for this SoC. Rename the USB controllers to the name actually used in the Rockchip documentation (USB OTGx) rather than the name blindly copied from Exynos code (USB DRDx). BRANCH=None BUG=chrome-os-partner:54621 TEST=Plug a USB 3.0 Patriot Memory stick into both ports in all orientations, observe how it gets reliably detected now (safe for some known hardware issues on my board).
