Remove the "no-map" property from the carveout DT node to have kernel and userspace mappings cached. This is currently a hack as I have not yet added a good way to clean these buffers out of the CPU cache. These should only be used on io-coherent platforms such as AM65x and J7x. Signed-off-by: -

commit b26ff913 upstream Rename ili251x_hardware_reset() to ili210x_hardware_reset(), change its parameter from struct device * to struct gpio_desc *, and use it as one single consistent reset implementation all over the driver. Also increase the minimum reset duration to 12ms, to make sure the reset is really within the spec. Signed-off-by:

commit 27931d38 upstream Modern devices may redraw display at 60 Hz, make sure we have one input sample per one frame. Reduce sample period to 15ms, so we would get up to 66.6 samples per second, although realistically with all the jitter and extra scheduling wiggle room, we would end up just above 60 samples per second. This should be a good compromise between sampling too often and sampling too seldom. Signed-off-by:

commit 8639e042 upstream Currently the ili210x driver implements a threaded interrupt handler which starts upon edge on the interrupt line, and then polls the touch controller for samples. Every time a sample is obtained from the controller, the thread function checks whether further polling is required, and if so, waits fixed amount of time before polling for next sample. The delay between consecutive samples can thus vary greatly, because the I2C transfer required to retrieve the sample from the controller takes different amount of time on different platforms. Furthermore, different models of the touch controllers supported by this driver require different delays during retrieval of samples too. Instead of waiting fixed amount of time before polling for next sample, determine how much time passed since the beginning of sampling cycle and then wait only the remaining amount of time within the sampling cycle. This makes the driver deliver samples with equal spacing between them. Signed-off-by:

commit de889108 upstream The ili251x touch controller needs 5ms delay between sending I2C device address and register address, and, writing or reading register data. According to downstream ili251x example code, this 5ms delay is not required when reading touch samples out of the controller. Implement such a special case. Signed-off-by:

commit c6ac8f0b upstream The ili251x firmware can be updated, this is used when switching between different modes of operation of the touch surface, e.g. glove operation. This patch implements the firmware update mechanism triggered by a write into an sysfs attribute. The firmware itself is distributed as an intel hex file with non-standard types. The first two lines are of type 0xad, which indicates the start of DataFlash payload, that is always at address 0xf000 on the ili251x, so it can be dropped, and 0xac which indicates the position of firmware info in the Application payload, that is always at address 0x2020 on the ili251x and we do not care. The rest of the firmware is data of type 0x00, and we care about that. To convert the firmware hex file into something usable by the kernel, remove the first two lines and then use ihex2fw: $ tail -n +3 input.hex > temp.hex $ ./tools/firmware/ihex2fw temp.hex firmware/ilitek/ili251x.bin To trigger the firmware update, place firmware file ilitek/ili251x.bin into /lib/firmware/, write into firmware_update sysfs attribute and wait about 30-40 seconds. The firmware update is slow. Afterward, verify the firmware_version and mode sysfs attributes to check whether the firmware got updated and the controller switched back to application (AP) mode by reading out 'mode' attribute in sysfs. Note that the content of firmware_version, e.g. 0600.0005.abcd.aa04 can be matched to the content of the firmware hex file. The first four bytes, 0x06 0x00 0x00 0x05 can be found at ^:102030 00 05000006, the next four bytes 0xab 0xcd 0xaa 0x04 at ^:10F000 00 nnnnnnnn ABCDAA04. Note that the protocol differs considerably between the ili2xxx devices, this patch therefore implements this functionality only for ili251x that I can test. Signed-off-by:

commit 70a7681d upstream The ili251x firmware protocol permits readout of firmware version, protocol version, mcu version and current mode (application, boot loader, forced update). These information are useful when updating the firmware on the il251x, e.g. to avoid updating the same firmware into the device multiple times. The locking is now necessary to avoid races between interrupt handler and the sysfs readouts. Note that the protocol differs considerably between the ili2xxx devices, this patch therefore implements this functionality only for ili251x that I can test. Signed-off-by:
-
commit 235300ed upstream The ili251x firmware protocol permits readout of panel resolution, implement this, but make it possible to override this value using DT bindings. This way, older DTs which contain touchscreen-size-x and touchscreen-size-y properties will behave just like before and new DTs may avoid specifying these for ILI251x. Note that the command format is different on other controllers, so this functionality is isolated to ILI251x. Signed-off-by:

The SERDES in SR1.0 supports 2 reference clocks. The second reference clock (core_ref1_clk) is hardwired to MAIN_PLL3_HSDIV4_CLKOUT (100/125/156.25 MHz). DM firmware update is required to set this clock to 156.25MHz for USXGMII support. Switch the SERDES wrapper device compatible to "ti,j7200-wiz-10g" to be aware of the additional reference clock and the special SCM register to manage the configuration i.e. "ti,scm" property. Switch the SERDES device compatible to "ti,j7200-serdes-10g" to support dual reference clock configurations. The SERDES clock configuration is not changed in this patch. Both the PLL reference clocks are still set to 100MHz (core_ref_clk) i.e. MAIN_PLL2_HSDIV4_CLKOUT. Later, when USXGMII is required the respective PLL reference clock can be switched to (core_ref1_clk) i.e. 156.25MHz while leaving the other PLL at 100MHz so PCIe/SGMII can continue to work.

SR2.0 has some differences than SR1.0. The current DT files will contain SR2.0 material and all SR1.0 specific differences will be held in these new overlay files. The usage model is same as in AM65. Silicon specific changes should be in DT overlay: k3-j7200-sr1.dts The SR1.0 specific board should include the above DT overlay file and then make any board specific changes if required. e.g.: k3-j7200-common-proc-board-sr1.dts SR2.0 specific changes in main device tree files will be added later.
