Message-Id: <1434668319-6651-1-git-send-email-stefan@agner.ch> Date: Fri, 19 Jun 2015 00:58:33 +0200 From: Stefan Agner <stefan@...er.ch> To: dwmw2@...radead.org, computersforpeace@...il.com Cc: sebastian@...akpoint.cc, robh+dt@...nel.org, pawel.moll@....com, mark.rutland@....com, ijc+devicetree@...lion.org.uk, galak@...eaurora.org, shawn.guo@...aro.org, kernel@...gutronix.de, boris.brezillon@...e-electrons.com, marb@...at.de, aaron@...tycactus.com, bpringlemeir@...il.com, linux-mtd@...ts.infradead.org, devicetree@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Stefan Agner <stefan@...er.ch> Subject: [PATCH v6 0/6] mtd: nand: vf610_nfc: Freescale NFC for VF610 The sixth revision has some minor changes, removing some worthless optimization and a compatible string. In the fifth revision some more changes, which have been made in the U-Boot driver, have been applied to this driver too. The driver now uses dedicated vf610_nfc_read_page/vf610_nfc_write_page functions which feel more appropriate for the device. This changes enable raw page writes, which in turn enables to use the the mtd_nandbiterrs.ko test. Beside that, the changes from the reviews have been implemented. If one is interested in the individual changes, the U-Boot patchset, which has been applied/adopted and squashed into this driver, is available in the U-Boot mailing list archive: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/220416 The patchset is based on the patchset by Bill Pringlemeir, see: http://thread.gmane.org/gmane.linux.ports.arm.kernel/295419 The driver passes the MTD tests, the logs are attched inline, below the change log. Performance key points on Colibri VF61: mtd_speedtest: testing eraseblock write speed mtd_speedtest: eraseblock write speed is 5417 KiB/s mtd_speedtest: testing eraseblock read speed mtd_speedtest: eraseblock read speed is 13012 KiB/s mtd_speedtest: testing page write speed Changes since v5: - Removed fsl,mpc5125-nfc compatible string - Removed readl/writel_relaxed - Change interface of vf610_nfc_transfer_size to match other accessors Changes since v4: - Rebased ontop of l2-mtd/master (v4.1-rc4 based) - Eliminate unnecessary page read (NAND_CMD_SEQIN) since the driver does not support sub-page writes anyway (improves write performance) - Support ONFI by enabling READID command with offset and parameter page reads (CMD_PARAM) - Change to dedicated read_page/write_page function, enables raw writes - Use __LITTLE_ENDIAN to distingush between LE/BE relevant statements - Eliminated vf610_nfc_probe_dt in favor of common DT init code - Use wait_for_completion_timeout - Some style fixes (spaces, etc.) Changes since v3: - Make the driver selectable when COMPILE_TEST is set - Fix compile error due to superfluous ECC_STATUS configuration in initial patch (without ECC correction ECC_STATUS does not need to be configured) - Remove custom BBT pattern and switch to in-band BBT in the initial patch - Include two bug fixes, for details see the corresponding U-Boot patches: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/215802 Changes since v2: - Updated binding documentation Changes since v1: - Nest nfc_config struct within the main nfc struct - Use assigned clock binding to specify NFC clock - Rebased ontop of MSCM IR patchset (driver parts have been merged) - Split out arch Kconfig in a separate config - Fix module license - Updated MAINTAINERS Changes since RFC (Bill Pringlemeir): - Renamed driver from fsl_nfc to vf610_nfc - Use readl/writel for all register in accessor functions - Optimized field accessor functions - Implemented PM (suspend/resume) functions - Implemented basic support for ECC strength/ECC step size from dt - Improved performance of count_written_bits by using hweight32 - Support ECC with 60-bytes to correct up to 32 bit errors - Changed to in-band BBT (NAND_BBT_NO_OOB) which also allows ECC modes which uses up to 60 bytes on 64 byte OOB - Removed custom (downstream) BBT pattern since BBT table won't be compatible anyway (due to the change above) MTD tests: [ 197.039235] ================================================== [ 197.045208] mtd_nandbiterrs: MTD device: 3 [ 197.066559] mtd_nandbiterrs: MTD
