2020-01-27spi: cadence-qspi: Add compatible for TI AM654Vignesh Raghavendra

2020-01-27mtd: spi-nor-core: Add octal mode supportVignesh Raghavendra

2020-01-27spi: cadence-qspi: Add direct mode supportVignesh Raghavendra
Add support for Direct Access Controller mode of Cadence QSPI. This allows MMIO access to SPI NOR flash providing better read performance. Direct mode is only exercised if AHB window size is greater than 8MB. Support for flash address remapping is also not supported at the moment and can be added in future. For better performance, driver uses DMA to copy data from flash in direct mode using dma_memcpy().

2020-01-27spi: cadence_qspi: Move to spi-mem frameworkVignesh Raghavendra
Current Cadence QSPI driver has few limitations. It assumes all read operations to be in Quad mode and thus does not support SFDP parsing. Also, adding support for new mode such as Octal mode would not be possible with current configuration. Therefore move the driver over to spi-mem framework. This has added advantage that driver can be used to support SPI NAND memories too. Hence, move driver over to new spi-mem APIs. Please note that this gets rid of mode bit setting done when CONFIG_SPL_SPI_XIP is defined as there does not seem to be any user to that config option.

2020-01-27spi: prevent overriding established bus settingsMarcin Wojtas
The SPI stack relies on a proper bus speed/mode configuration by calling dm_spi_claim_bus(). However the hitherto code allowed to accidentally override those settings in the spi_get_bus_and_cs() routine. The initially established speed could be discarded by using the slave platdata, which turned out to be an issue on the platforms whose slave maximum supported frequency is not on par with the maximum frequency of the bus controller. This patch fixes above issue by configuring the bus from spi_get_bus_and_cs() only in case it was not done before.

2020-01-27spi: nxp_fspi: new driver for the FlexSPI controllerMichael Walle
This is a port of the kernel's spi-nxp-fspi driver. It uses the new spi-mem interface and does not expose the more generic spi-xfer interface. The source was taken from the v5.3-rc3 tag. The port was straightforward: - remove the interrupt handling and the completion by busy polling the controller - remove locks - move the setup of the memory windows into claim_bus() - move the setup of the speed into set_speed() - port the device tree bindings from the original fspi_probe() to ofdata_to_platdata() There were only some style change fixes, no change in any logic. For example, there are busy loops where the return code is not handled correctly, eg. only prints a warning with WARN_ON(). This port intentionally left most functions unchanged to ease future bugfixes. This was tested on a custom LS1028A board. Because the LS1028A doesn't have proper clock framework support, changing the clock speed was not tested. This also means that it is not possible to change the SPI speed on LS1028A for now (neither is it possible in the linux driver).

2020-01-26sunxi: Automate loading from 128KB MMC offsetAndre Przywara
Since commit 067e0b9684d4 ("sunxi: Allow booting from 128KB SD/eMMC offset") we support having the SPL loaded from either the traditional 8KB SD card/eMMC offset, or from the alternative location at 128KB. However the sector to find the U-Boot image was still hard-coded at compile time, and had to be adjusted for one of the two choices. Since we can actually override the function to return the sector offset, we can just check the boot source byte there to select the proper offset based on from where the SPL was loaded. This allows the very same binary image to be loaded from either 128KB or 8KB, with the U-Boot proper image always being located just behind the SPL.

2020-01-26clk: mediatek: use unsigned type for returning the clk rateFabien Parent
mtk_clk_find_parent_rate is calling clk_get_rate to know the rate of a parent clock. clk_get_rate returns a ulong, while mtk_clk_find_parent_rate returns an int. This implicit cast creates an issue for clock rates big enough to need the full 32 bits to store its data. When that happen the clk rate will become incorrect because of the implicit cast between ulong -> int -> ulong. This commit change the return type of mtk_clk_find_parent_rate to ulong.
