2019-02-14i2c: tegra: add i2c interface timing supportSowjanya Komatineni1-30/+159
This patch adds I2C interface timing registers support for proper bus rate configuration along with meeting the I2C spec setup and hold times based on the tuning performed on Tegra210, Tegra186 and Tegra194 platforms. I2C_INTERFACE_TIMING_0 register contains TLOW and THIGH field and Tegra I2C controller design uses them as a part of internal clock divisor. I2C_INTERFACE_TIMING_1 register contains the setup and hold times for start and stop conditions.

2019-02-14i2c: tegra: update transfer timeoutSowjanya Komatineni1-4/+11
Tegra194 allows max of 64K bytes and Tegra186 and prior allows max of 4K bytes of transfer per packet. one sec timeout is not enough for transfers more than 10K bytes at STD bus rate. This patch updates I2C transfer timeout based on the transfer size and I2C bus rate to allow enough time during max transfer size at lower bus speed.

2019-02-14i2c: tegra: Add DMA supportSowjanya Komatineni1-49/+383
This patch adds DMA support for Tegra I2C. Tegra I2C TX and RX FIFO depth is 8 words. PIO mode is used for transfer size of the max FIFO depth and DMA mode is used for transfer size higher than max FIFO depth to save CPU overhead. PIO mode needs full intervention of CPU to fill or empty FIFO's and also need to service multiple data requests interrupt for the same transaction. This adds delay between data bytes of the same transfer when CPU is fully loaded and some slave devices has internal timeout for no bus activity and stops transaction to avoid bus hang. DMA mode is helpful in such cases. DMA mode is also helpful for Large transfers during downloading or uploading FW over I2C to some external devices. Tegra210 and prior Tegra chips use APBDMA driver which is replaced with GPCDMA on Tegra186 and Tegra194. This patch uses has_apb_dma flag in hw_feature to differentiate DMA driver change between Tegra chipset. APBDMA driver is registered from module-init level and this patch also has a change to register I2C driver at module-init level rather than subsys-init to avoid deferring I2C probe till APBDMA driver is registered.

2019-02-14i2c: tegra: add bus clear Master SupportSowjanya Komatineni1-0/+81
Bus clear feature of Tegra I2C controller helps to recover from bus hang when I2C master loses the bus arbitration due to the slave device holding SDA LOW continuously for some unknown reasons. Per I2C specification, the device that held the bus LOW should release it within 9 clock pulses. During bus clear operation, Tegra I2C controller sends 9 clock pulses and terminates the transaction with STOP condition. Upon successful bus clear operation, bus goes to idle state and driver retries the transaction.

2019-02-05i2c: of: Try to find an I2C adapter matching the parentThierry Reding1-1/+13
If an I2C adapter doesn't match the provided device tree node, also try matching the parent's device tree node. This allows finding an adapter based on the device node of the parent device that was used to register it. This fixes a regression on Tegra124-based Chromebooks (Nyan) where the eDP controller registers an I2C adapter that is used to read to EDID. After commit 993a815dcbb2 ("dt-bindings: panel: Add missing .txt suffix") this stopped working because the I2C adapter could no longer be found. The approach in this patch fixes the regression without introducing the issues that the above commit solved.

This is because pixcir_ts tries to reconfigure it's registers for noirq suspend which fails. This also leaves i2c-omap in enabled state for suspend. Let's fix the pixcir_ts issue and make sure i2c-omap is suspended by adding SET_NOIRQ_SYSTEM_SLEEP_PM_OPS. Let's also get rid of some ifdefs while at it and replace them with __maybe_unused as SET_RUNTIME_PM_OPS and SET_NOIRQ_SYSTEM_SLEEP_PM_OPS already deal with the various PM Kconfig options.
