Rockchp's NFC(Nand Flash Controller) has four versions: V600, V622, V800 and V900.This series patch can support all four versions. Changes in v16: - Fix some comments about 'ret' variable. Changes in v15: - Use a buffer pointer nfc->page_buf instead of the original two pointers. - Fix coding style. - Fix some comments. Changes in v14: - Add oob_read and oob_write hook api. - Support timing config and ecc config for each chips. - Fix some comments. Changes in v13: - The nfc->buffer will realloc while the page size of the second mtd is large than the first one. - Fix coding style. - Fix some comments. Changes in v12: - Fix some warnings while make dt_binding_check - Drop a allOf defined Changes in v11: - Fix compile error. Changes in v10: - Fix compile error on master v5.9-rc7. Changes in v9: - The nfc->buffer will realloc while the page size of the second mtd is large than the first one - Fix coding style. - Remove struct rk_nfc_clk. - Prepend some function with rk_nfc_. - Replace function readl_poll_timeout_atomic with readl_relaxed_poll_timeout. - Remove function rk_nfc_read_byte and rk_nfc_write_byte. - Don't select the die if 'check_only == true' in function rk_nfc_exec_op. - Modify function rk_nfc_write_page and rk_nfc_write_page_raw. Changes in v8: - Fix a error while make dt_binding_check Changes in v7: - Fix some wrong define - Rebase to linux-next. - Fix coding style. - Reserved 4 bytes at the beginning of the oob area. - Page raw read and write included ecc data. Changes in v6: - Fix some wrong define - Modified the definition of compatible - The mtd->name set by NAND label property. - Add some comments. - Fix compile error. Changes in v5: - Fix some wrong define. - Add boot-medium define. - Remove some compatible define. - Add boot blocks support with different ECC for bootROM. - Rename rockchip-nand.c to rockchip-nand-controller.c. - Unification of other variable names. - Remove some compatible define. Changes in v4: - The compatible define with rkxx_nfc. - Add assigned-clocks. - Fix some wrong defineChanges in. - Define platform data structure for the register offsets. - The compatible define with rkxx_nfc. - Use SET_SYSTEM_SLEEP_PM_OPS to define PM_OPS. - Use exec_op instead of legacy hooks. Changes in v3: - Change the title for the dt-bindings. Changes in v2: - Fix compile error. - Include header files sorted by file name.
