* mtd: spi-nor: introduce SPI 1-2-2 and SPI 1-4-4 protocolsSteffen Trumtrar2019-05-083-204/+511
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sync the driver with Linux v4.12 and apply the patch commit cfc5604c488ccd17936b69008af0c9ae050f4a08 Author: Cyrille Pitchen <cyrille.pitchen@atmel.com> AuthorDate: Tue Apr 25 22:08:46 2017 +0200 Commit: Cyrille Pitchen <cyrille.pitchen@wedev4u.fr> CommitDate: Mon May 15 21:56:17 2017 +0200 mtd: spi-nor: introduce SPI 1-2-2 and SPI 1-4-4 protocols This patch changes the prototype of spi_nor_scan(): its 3rd parameter is replaced by a 'struct spi_nor_hwcaps' pointer, which tells the spi-nor framework about the actual hardware capabilities supported by the SPI controller and its driver. Besides, this patch also introduces a new 'struct spi_nor_flash_parameter' telling the spi-nor framework about the hardware capabilities supported by the SPI flash memory and the associated settings required to use those hardware caps. Then, to improve the readability of spi_nor_scan(), the discovery of the memory settings and the memory initialization are now split into two dedicated functions. 1 - spi_nor_init_params() The spi_nor_init_params() function is responsible for initializing the 'struct spi_nor_flash_parameter'. Currently this structure is filled with legacy values but further patches will allow to override some parameter values dynamically, for instance by reading the JESD216 Serial Flash Discoverable Parameter (SFDP) tables from the SPI memory. The spi_nor_init_params() function only deals with the hardware capabilities of the SPI flash memory: especially it doesn't care about the hardware capabilities supported by the SPI controller. 2 - spi_nor_setup() The second function is called once the 'struct spi_nor_flash_parameter' has been initialized by spi_nor_init_params(). With both 'struct spi_nor_flash_parameter' and 'struct spi_nor_hwcaps', the new argument of spi_nor_scan(), spi_nor_setup() computes the best match between hardware caps supported by both the (Q)SPI memory and controller hence selecting the relevant settings for (Fast) Read and Page Program operations.

* spi: add driver for Freescale QSPI controllerSteffen Trumtrar2019-05-083-0/+881
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is based on the Linux v5.1-rc1 driver introduced with the commit: commit 84d043185dbe0d1b4f6db575bd91c834d37e2f78 Refs: v5.0-rc1-1-g84d043185dbe Author: Frieder Schrempf <frieder.schrempf@kontron.de> AuthorDate: Mon Jan 7 09:29:47 2019 +0000 Commit: Mark Brown <broonie@kernel.org> CommitDate: Mon Jan 7 16:56:24 2019 +0000 spi: Add a driver for the Freescale/NXP QuadSPI controller This driver is derived from the SPI NOR driver at mtd/spi-nor/fsl-quadspi.c. It uses the new SPI memory interface of the SPI framework to issue flash memory operations to up to four connected flash chips (2 buses with 2 CS each). The controller does not support generic SPI messages. This patch also disables the build of the "old" driver and reuses its Kconfig option CONFIG_SPI_FSL_QUADSPI to replace it.

This is the barebox adoption of the commit commit c36ff266dc82f4ae797a6f3513c6ffa344f7f1c7 Author: Boris Brezillon <boris.brezillon@bootlin.com> Date: Thu Apr 26 18:18:14 2018 +0200 spi: Extend the core to ease integration of SPI memory controllers Some controllers are exposing high-level interfaces to access various kind of SPI memories. Unfortunately they do not fit in the current spi_controller model and usually have drivers placed in drivers/mtd/spi-nor which are only supporting SPI NORs and not SPI memories in general. This is an attempt at defining a SPI memory interface which works for all kinds of SPI memories (NORs, NANDs, SRAMs).

This is the barebox adoption of the commit commit 8caab75fd2c2a92667cbb1cd315720bede3feaa9 Author: Geert Uytterhoeven <geert+renesas@glider.be> Date: Tue Jun 13 13:23:52 2017 +0200 spi: Generalize SPI "master" to "controller" Now struct spi_master is used for both SPI master and slave controllers, it makes sense to rename it to struct spi_controller, and replace "master" by "controller" where appropriate. For now this conversion is done for SPI core infrastructure only. Wrappers are provided for backwards compatibility, until all SPI drivers have been converted. Noteworthy details: - SPI_MASTER_GPIO_SS is retained, as it only makes sense for SPI master controllers, - spi_busnum_to_master() is retained, as it looks up masters only, - A new field spi_device.controller is added, but spi_device.master is retained for compatibility (both are always initialized by spi_alloc_device()), - spi_flash_read() is used by SPI masters only.

They are defined with external linkage. With '-Wmissing-prototypes' GCC warns about externally linked function definitions with no preceding prototype. Define them as 'static inline' to avoid the compiler warnings. (Note: Arria10 uses non-dummy versions of these functions declared 'extern' but defined elsewhere.)

| * | | ARM: stm32mp1: Add clk driverSascha Hauer2019-03-112-0/+1989
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Taken from Linux v5.0-rc2. Mostly as-is, only adopted to the differences between the Linux and barebox clk API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | clk: mux: Support CLK_SET_RATE_NO_REPARENT flagSascha Hauer2019-03-112-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since barebox doesn't do reparenting on rate changes we only have to define the flag. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | clk: mux: Support CLK_MUX_READ_ONLY flagSascha Hauer2019-03-111-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | Support readonly dividers using the CLK_MUX_READ_ONLY flag. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | clk: mux: Support mux specific flagsSascha Hauer2019-03-116-24/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We'll need mux specific flags in the future, so add a parameter to the mux initialization functions. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | clk: divider: Support CLK_DIVIDER_READ_ONLY flagSascha Hauer2019-03-113-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | To support a readonly divider add the CLK_DIVIDER_READ_ONLY flag. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
