| | | | | | | | | | | | | | | | | | | | | | | | | | | We've never tested the lvds panel support on sun6i+ SoCs until now, and unsurprisingly the lvds code needed some fixes to work on my ga10h A33 tablet with lvds panel.

* | | sunxi: Make DRAM_ODT_EN Kconfig setting a boolHans de Goede2015-05-19-16/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make DRAM_ODT_EN Kconfig setting a bool, add a separate DRAM_ODT_CORRECTION setting for A23 SoCs and use DRAM_ODT_EN Kconfig everywhere instead of only in dram_sun4i.c and hardcoding odt_en elsewhere. Note this commit makes no functional changes for existing boards, its purpose is to allow changing the odt_en value on future A33 boards. For sun4i/sun5i/sun7i boards which set DRAM_ODT_EN=y (which no defconfigs currently do) this patch turns on odt for both the DQ and the DQS lines, whereas previously it was possibly (but not desirable) to turn odt on only for one of them by setting the in DRAM_ODT_EN option to 1 or 2 instead of 3.

* | mx6: Set shared override bit in PL310 AUX_CTRL registerFabio Estevam2015-05-15-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having bit 22 cleared in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. This was inspired by a patch from Catalin Marinas [1] and also from recent discussions in the linux-arm-kernel list [2] where Russell King and Rob Herring suggested that bootloaders should initialize the cache.

* | arm: mx6: Clamp MMDC and DDR3 clocks for timing calculationsNikolay Dimitrov2015-05-15-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is proposal for clamping the MMDC/DDR3 clocks to the maximum supported frequencies as per imx6 SOC models, and for dynamically calculating valid clock value based on mem_speed. Currently the code uses impossible values for mem_speed (1333, 1600 MT/s) for calculating the DDR timings, and uses fixed clock (528 or 400 MHz) which doesn't take into account DDR3 memory limitations.

Introduce a new structure `struct mxc_i2c_bus`, this structure will used for non-DM and DM. 2. Remove `struct mxc_i2c_regs` structure, but use register offset to access registers based on `base` entry of `struct mxc_i2c_bus`. 3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform flags. A new flag is introduced, I2C_QUIRK_FLAG. 4. Most functions use `struct mxc_i2c_bus` as one of the parameters. Make most functions common to DM and non-DM, try to avoid duplicated code. 5. Support DM, but pinctrl is not included. Pinmux setting is still set by setup_i2c, but we do not need bus_i2c_init for DM. 6. struct i2c_parms and struct sram_data are removed. 7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist paramter of bus_i2c_init is modified to i2c index. Add new prototype i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus. Board file take the responsibility to implement this function, like this: " int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus) { if (i2c_bus->index == 0) force_bus_idle(i2c_pads_info0); else if (i2c_bus->index == 1) force_bus_idle(i2c_pads_info1); else xxxxxx } " 8. Introduce a weak function, enable_i2c_clk 9. Tested on an i.MX7 platform.

Also, imx-regs.h and iomux-v3.h has same macro defintion for GPIO_PORTx, and both of them are included in mxc_i2c.c(include mxc_i2c.h). This will incur build warnings with macro redefinition. Since iomux-v3.h is not compatible with mx27, we can not simply include iomux-v3.h for mx27, so move the GPIO_PORTx to gpio.h to fix the build warning.

So instead I have added a new weak arch function protect_secure_section() called from relocate_secure_section() and reserved the region there. This is better overall since it defers the reservation until after the sec vs. non-sec decision (which can be influenced by an envvar) has been made when booting the os.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _sunxi_cpu_entry can be converted completely into a reusable psci_cpu_entry. Tegra124 will use it as well. As with psci_disable_smp, also the enabling is designed to be overloaded in cased SMP is not controlled via ACTLR.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move parts of sunxi's psci_cpu_off into psci_cpu_off_common, namely cache disabling and flushing, clrex and the disabling of SMP for the dying CPU. These steps are apparently generic for ARMv7 and will be reused for Tegra124 support. As the way of disabled SMP is not architectural, though commonly done via ACLTR, the related function can be overloaded.
