memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing

2016-07-27T16:47:35Z

commit 8f50b8e57442d28e41bb736c173d8a2490549a82 upstream. In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY is overwritten by the WEEXTRADELAY value from the device tree and GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device tree. As a consequence, the memory accesses cannot be configured properly when the extra delay are needed for OE and WE. Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the device tree file and prevents GPMC_CONFIG4_OEXTRADELAY being overwritten by the WEXTRADELAY value from the device tree.

Pull ARM SoC driver updates from Olof Johansson: "As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere. Many of them go in through other driver trees, but we still have drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code that might be shared between ARM and ARM64 (or just in general makes sense to not have under the architecture directory). This branch contains mostly such code: - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate with power management blocks on these SoCs for use by clock, regulator and bus frequency drivers. - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs. - Drivers for ARM's SCPI (System Control Processor). Not to be confused with PSCI (Power State Coordination Interface). SCPI is used to communicate with the assistant embedded cores doing power management, and we have yet to see how many of them will implement this for their hardware vs abstracting in other ways (or not at all like in the past). - To make confusion between SCPI and PSCI more likely, this release also includes an update of PSCI to interface version 1.0. - Rockchip support for power domains. - A driver to talk to the firmware on Raspberry Pi" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (57 commits) soc: qcom: smd-rpm: Correct size of outgoing message bus: sunxi-rsb: Add driver for Allwinner Reduced Serial Bus bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings ARM: bcm2835: add mutual inclusion protection drivers: psci: make PSCI 1.0 functions initialization version dependent dt-bindings: Correct paths in Rockchip power domains binding document soc: rockchip: power-domain: don't try to print the clock name in error case soc: qcom/smem: add HWSPINLOCK dependency clk: berlin: add cpuclk ARM: berlin: dts: add CLKID_CPU for BG2Q ARM: bcm2835: Add the Raspberry Pi firmware driver soc: qcom: smem: Move RPM message ram out of smem DT node soc: qcom: smd-rpm: Correct the active vs sleep state flagging soc: qcom: smd: delete unneeded of_node_put firmware: qcom-scm: build for correct architecture level soc: qcom: smd: Correct SMEM items for upper channels qcom-scm: add missing prototype for qcom_scm_is_available() qcom-scm: fix endianess issue in __qcom_scm_is_call_available soc: qcom: smd: Reject send of too big packets soc: qcom: smd: Handle big endian CPUs ...

memory: omap-gpmc: dump "before" state before first modification

2015-10-12T23:23:34Z

When gpmc_cs_show_timings is called in gpmc_cs_set_timings() gpmc_cs_program_settings() was already run which modifies the CONFIG1 register. So to be more useful do the "before" dump earlier. Signed-off-by: Uwe Kleine-König Acked-by: Roger Quadros Signed-off-by: Tony Lindgren

memory: omap-gpmc: Fix unselectable debug option for GPMC

2015-10-12T23:19:54Z

Commit 63aa945b1013 ("memory: omap-gpmc: Add Kconfig option for debug") added a debug option for GPMC, but somehow managed to keep it unselectable. This probably happened because I had some uncommitted changes and the GPMC option is selected in the platform specific Kconfig. Let's also update the description a bit, it does not mention that enabling the debug option also disables the reset of GPMC controller during the init as pointed out by Uwe Kleine-König and Roger Quadros .

memory: pl172: add ARM PrimeCell PL176 MPMC support

2015-09-29T20:19:02Z

The change adds support of ARM PrimeCell PL176 MPMC. Static memory configuration of PL175 MPMC is very similar to one found on PL172 and PL175 controllers, so it is preferred to add its support into the existing driver. The difference is that PL176 supports up to 10 slave ports (but only 4 of them may be connected to static memory devices), AHB master bus width cab be 64-bit wide, also NAND devices can be interfaced. Similar to PL175 contoller, PL176 has no write buffer enable control in static memory configuration register, the rest of static memory configuration bits (with exception of NAND) is the same.

The change adds support of ARM PrimeCell PL175 MPMC, the controller is found on NXP LPC32xx SoC. PL175 MPMC is very similar to PL172 controller, so it is preferred to add its support into the existing driver. One of the differences between PL172 and PL175 is that the latter one supports up to 6 AHB ports, but still only 4 AHB ports can be assigned to a static memory device, also PL175 does not have write buffer enable control in static memory configuration register.
