* | mfd: rave-sp: Add parameters to query IP address/netmaskAndrey Smirnov2018-12-131-0/+72
|/ | | | | | | | | | | | Unlike LCD type information, IP address as well as netmaks are not stored in an easily usable format in RAVE SP EEPROM. In order to obtain them we need to issue a special command to RAVE SP. For that purpose add device "sp" and expose that data as a device parameters (sp.ipaddr and sp.netmask, correspondingly) Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mfd: rave-sp: Emulate CMD_GET_STATUS on device that don't support itAndrey Smirnov2018-08-311-34/+66
| | | | | | | | | | | | | | CMD_GET_STATUS is not supported by some devices implementing RDU2-compatible ICD as well as "legacy" devices. To account for that fact, add code that obtains the same information (app/bootloader FW version) using several different commands. This is a backport of Linux kernel patch [1] [1] https://lore.kernel.org/lkml/20180707024108.32373-5-andrew.smirnov@gmail.com/T/#md1b7130a992235d57cabadc8e59fc74ee3b21d9e Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mfd: rave-sp: Add legacy watchdog ping command translationAndrey Smirnov2018-08-311-0/+2
| | | | | | | | | | | | This is needed to make rave-sp-wdt driver to properly ping the watchdog on "legacy" firmware. This is a backport of Linux kernel patch [1] [1] https://lore.kernel.org/lkml/20180707024108.32373-5-andrew.smirnov@gmail.com/T/#m767615239f8aa681a2dc0ccfe1c877e4cbb0edf6 Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mfd: rave-sp: Add mapping for legacy EEPROM commandAndrey Smirnov2018-08-311-0/+2
| | | | | | | | | | | | This is needed to make rave-sp-eeprom driver work on "legacy" firmware. This is a backport of Linux kernel patch [1] [1] https://lore.kernel.org/lkml/20180707024108.32373-5-andrew.smirnov@gmail.com/T/#mae2272763ae092b5b11ab128f5c22039d55557cb Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mfd: rave-sp: Fix incorrectly specified checksum typeAndrey Smirnov2018-08-311-1/+1
| | | | | | | | | | | | RAVE SP firmware covered by "legacy" variant uses 16-bit CCITT checksum algorithm. Change the code to correctly reflect that.
