media: imx-jpeg: Support dynamic resolution change

2022-05-13T09:02:19Z

To support dynamic resolution change, driver should meet the following conditions: 1. the previous pictures are all decoded before source change event. 2. prevent decoding new resolution pictures with incorrect capture buffer, until user handle source change event and setup capture. 3. report correct fmt and resolution during source change.

media: imx-jpeg: Identify and handle precision correctly

2022-05-13T09:02:18Z

The decoder will save the precision that was detected from jpeg header and use it later, when choosing the pixel format and also calculate bytesperline according to precision. The 12bit jpeg is not supported yet, but driver shouldn't led to serious problem if user enqueue a 12 bit jpeg. And the 12bit jpeg is supported by hardware, driver may support it later.

media: imx: imx-mipi-csis: Protect mipi_csis_dump_regs()

2022-04-24T08:06:41Z

The mipi_csis_dump_regs() function accesses the interface registers in order to printout their values for debug purposes. As the function access the registers, it requires the interface to be powered up. Currently this is only enforced in one of the function's callers (mipi_csis_log_status)() but not when the function is called by the debugfs attribute handler. Make sure to access registers only if the interface is powered up and remove the same check from the caller.
