mtd: rawnand: Increment IFC_TIMEOUT_MSECS for nand controller response
[ Upstream commit 923fb6238cb3ac529aa2bf13b3b1e53762186a8b ] Under heavy load it is likely that the controller is done with its own task but the thread unlocking the wait is not scheduled in time. Increasing IFC_TIMEOUT_MSECS allows the controller to respond within allowable timeslice of 1 sec. fsl,ifc-nand 7e800000.nand: Controller is not responding [<804b2047>] (nand_get_device) from [<804b5335>] (nand_write_oob+0x1b/0x4a) [<804b5335>] (nand_write_oob) from [<804a3585>] (mtd_write+0x41/0x5c) [<804a3585>] (mtd_write) from [<804c1d47>] (ubi_io_write+0x17f/0x22c) [<804c1d47>] (ubi_io_write) from [<804c047b>] (ubi_eba_write_leb+0x5b/0x1d0) Fixes: 82771882d960 ("NAND Machine support for Integrated Flash Controller") Reviewed-by: Miquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Ronald Monthero <debug.penguin32@gmail.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20231118083156.776887-1-debug.penguin32@gmail.com Signed-off-by: Sasha Levin <sashal@kernel.org>
