i3c: master: svc: Fix error code in svc_i3c_master_do_daa_locked()

2024-07-26T12:21:30Z

This code has a typo so it returns positive EIO instead of negative -EIO. Fix it!

i3c: dw: Add power management support

2024-07-26T12:21:30Z

Add support for runtime and system power management. Handle clocks, resets, pads as part of suspend and resume. Restore controller registers that could be lost due to suspend. Finally add get and put calls appropriately in functions which access controller : bus_init, do_daa, send_ccc_cmd, priv_xfers, i2c_xfers, ibi and hot-join.

i3c: dw: Add some functions for reusability

2024-07-26T12:21:30Z

Separate logic for setting intr/thld registers in a func. Also modify enable function to take care of setting all fields in DEVICE_CTRL. These functions can be reused later for power management.

i3c: dw: Save timing registers and other values

2024-07-26T12:21:29Z

Add variables to store timing registers and other values. These variables would be later used to restore registers during resume without recomputation. Signed-off-by: Aniket Link: https://lore.kernel.org/r/20240708062103.3296587-2-aniketmaurya@google.com Signed-off-by: Alexandre Belloni

i3c: master: svc: Improve DAA STOP handle code logic

2024-07-26T12:21:29Z

The REQUEST_PROC_DAA command behaves differently from other commands. Sometimes the hardware can auto emit STOP, but in other conditions, it cannot. Improves the code logic to better handle these situations. Hardware can auto emit STOP only when the following conditions are met: - The previous I3C device correctly returns a PID and ACKs an I3C address. - A NACK is received when emitting 7E to try to get the next I3C device's PID. In all other cases, a manual STOP emission is needed. The code is changed to emit STOP when break the while loop and 'return 0' only when the hardware can auto emit STOP.

i3c: dw: Add optional apb clock

i3c: mipi-i3c-hci: Round IBI data chunk size to HW supported value

2024-07-26T12:21:29Z

The dma.c: hci_dma_init() sets the CHUNK_SIZE field in the IBI_SETUP register incorrectly if the calculated ibi_chunk_sz is not exactly 2^(n+2) bytes, where n is 0..6. Fix this by rounding the chunk size up to nearest 2^(n+2) bytes.
