* nvmem: imx-ocotp: Update module descriptionBryan O'Donoghue2017-11-081-1/+1
| | | | | | | | | | | This imx-ocotp driver encapsulates support for a subset of both i.MX6 and i.MX7 processors. Update the module description to reflect. Fixes: 711d45477931 ("nvmem: octop: Add i.MX7D support") Signed-off-by: Bryan O'Donoghue <pure.logic@nexus-software.ie> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* nvmem: imx-ocotp: Enable i.MX7D OTP write supportBryan O'Donoghue2017-11-081-2/+0
| | | | | | | | | | | After applying patches for both banked access and write timings we can re-enable the OTP write interface on i.MX7D processors.

| | | | | | | | | | | This patch adds logic to correctly setup the write timing parameters when blowing an OTP fuse for the i.MX7S/D.

* nvmem: imx-ocotp: Move i.MX6 write clock setup to dedicated functionBryan O'Donoghue2017-11-081-20/+27
| | | | | | | | | | | | | The i.MX7S/D has a different set of timing requirements, as a pre-cursor to adding the i.MX7 timing parameters, move the i.MX6 stuff to a dedicated function.

* nvmem: imx-ocotp: Add support for banked OTP addressingBryan O'Donoghue2017-11-081-4/+64
| | | | | | | | | | | | | | The i.MX7S/D takes the bank address in the CTRLn.ADDR field and the data value in one of the DATAx {0, 1, 2, 3} register fields. The current write routine is based on writing the CTRLn.ADDR field and writing a single DATA register only.

* nvmem: imx-ocotp: Restrict OTP write to IMX6 processorsBryan O'Donoghue2017-11-081-0/+2
| | | | | | | | | | | | | | | | i.MX7S/D have a different scheme for addressing the OTP registers inside the OCOTP block. Currently it's possible to address the wrong OTP registers given the disparity between IMX6 and IMX7 OTP addressing. Since OTP programming is one-time destructive its important we restrict this interface ASAP.

* nvmem: set nvmem->owner to nvmem->dev->driver->owner if unsetMasahiro Yamada2017-11-0813-12/+2
| | | | | | | | | | | | | | | All nvmem drivers are supposed to set the owner field of struct nvmem_config, but this matches nvmem->dev->driver->owner. As far as I see in drivers/nvmem/ directory, all the drivers are the case. So, make nvmem_register() set the nvmem's owner to the associated driver's owner unless nvmem_config sets otherwise. Remove .owner settings in the drivers that are now redundant.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current shift of st->rx[2] left shifts a u8 24 bits left, promotes the integer to a an int and then to a unsigned u64. If the top bit of st->rx[2] is set then we end up with all the upper bits being set to 1. Fix this by casting st->rx[2] to a u64 before the 24 bit left shift.

But (some version of) gcc is not smart enough to notice. Remove the check to fix this. As there is no other code in between assigning the error codes and returning them, the error codes can be returned immediately, and the intermediate variable can be dropped. Drop the "else" to please checkpatch.

Also default settings to POR defaults on a reset, and register distuber interrupts as noise since it prevents proper usage.
