It just makes NAND maintainers' life easier by allowing them to compile-test this driver without having SOC_TX4938 or SOC_TX4939 enabled. We also need to add a dependency on HAS_IOMEM to make sure the driver compiles correctly. Signed-off-by:

uintptr_t should be used when casting a pointer to an unsigned int so that the code compiles without warnings even on 64-bit architectures. This is needed if we want to allow selection of this driver when COMPILE_TEST=y. Signed-off-by:

We want to allow this driver to be selected when COMPILE_TEST=y, this means the driver can be compiled for any arch, including MIPS. When compiling this driver for MIPS, we end up with a collision on the 'PC' macro definition (also defined in arch/mips/include/asm/ptrace.h). Prefix the fsmc one with FSMC_ to avoid this problem.

There is no point in doing this sort of conversion since we can replace |= by += operations which are perfectly valid on pointers. This is done in preparation of COMPILE_TEST addition to the NAND_DAVINCI Kconfig entry, since building for x86 generates several warnings because of inappropriate u32 <-> void * conversions (pointers are 64-bit large on x86_64).

When casting a pointer to an unsigned int, uintptr_t should be used to cope with the pointer size differences between 32-bit and 64-bit architectures. This is needed if we want to allow compilation of this driver when COMPILE_TEST=y. Reported-by:

Modern NAND controller drivers implement ->exec_op() instead of ->cmdfunc(), make sure we don't end up with a NULL pointer dereference when hynix_nand_reg_write_op() is called. Fixes: 8878b126 ("mtd: nand: add ->exec_op() implementation") Cc: <stable@vger.kernel.org> Signed-off-by:

Don't keep an error-pointer around in the private struct. If this optional clock can't be obtained, simply set the pointer to NULL instead so we can use clk_prepare_enable() on it without further checks, Signed-off-by:

The comment in marvell_nfc_select_chip() about ndtr0 and ndtr1 didn't reflect what the driver was doing. The values of NDTR0 and NDTR1 are read from the registers at probe time and a copy is retained in 'struct marvell_nand_chip'. If keep-config is set in the DT properties, there are no other writers of these timing variables so they can safely be used when the chip is selected. As suggested by Miquel Raynal, simply remove the comment. Signed-off-by:

This patch restores the suspend and resume hooks that the old driver used to have. Apart from stopping and starting the clocks, the resume callback also nullifies the selected_chip pointer, so the next command that is issued will re-select the chip and thereby restore the timing registers. Factor out some code from marvell_nfc_init() into a new function marvell_nfc_reset() and also call it at resume time to reset some registers that don't retain their contents during low-power mode. Without this patch, a PXA3xx based system would cough up an error similar to the one below after resume.

This allows us to increase compile-test coverage without having to build a kernel for MIPS. That's particularly interesting for subsystem maintainers that want to test as many drivers as possible in a single build. We also add a dependency on HAS_IOMEM in BCMA_HOST_SOC to make sure the driver is not selected when the arch does not implement IO accessors. Signed-off-by:
