cros_ec: Handling EC_CMD_GET_NEXT_EVENT

2020-11-14T22:23:41Z

With commit 690079767803 ("cros_ec: Support keyboard scanning with EC_CMD_GET_NEXT_EVENT") check_for_keys() tries to read keyboard strokes using EC_CMD_GET_NEXT_EVENT. But the sandbox driver does not understand this command. We need to reply with -EC_RES_INVALID_COMMAND to force check_for_keys() to fall back to use EC_CMD_MKBP_STATE. Currently the driver prints ** Unknown EC command 0x67 in this case. With the patch the message is suppressed. In a future patch we should upgrade the sandbox driver to provide EC_CMD_GET_NEXT_EVENT support.

cros_ec: Increase command timeout for flash erase

2020-11-14T22:23:41Z

Erasing the flash can take over a second on some devices and the EC is not responsive during this time. Update the timeout to 5 seconds to cope with this. Signed-off-by: Simon Glass

cros_ec: Correct collection of EC hash

2020-11-14T22:23:41Z

The EC now requires that the offset field be set correctly when checking on hash status. Update the code to handle this. Use the same message struct in both functions to reduce stack space. Signed-off-by: Simon Glass

cros_ec: Support keyboard scanning with EC_CMD_GET_NEXT_EVENT

2020-11-05T16:11:31Z

The cros_ec_keyb driver currently uses EC_CMD_MKBP_STATE to scan the keyboard, but this host command was superseded by EC_CMD_GET_NEXT_EVENT and unavailable on more recent devices (including gru-kevin), as it was removed in cros-ec commit 87a071941b89 ("mkbp: Add support for buttons and switches.") dated 2016-07-06. The EC_CMD_GET_NEXT_EVENT has been available since cros-ec commit d1ed75815efe ("MKBP event signalling implementation") dated 2014-10-20, but it looks like it isn't included in firmware-* branches for at least link, nyan-big, samus, snow, spring, panther and peach-pit which have defconfigs in U-Boot. So this patch falls back to the old method if the EC doesn't recognize the newer command. The implementation is mostly adapted from Depthcharge commit f88af26b44fc ("cros_ec: Change keyboard scanning method."). On a gru-kevin, the current driver before this patch fails to read the pressed keys with: out: cmd=0x60: 03 9d 60 00 00 00 00 00 in-header: 03 fc 01 00 00 00 00 00 in-data: ec_command_inptr: len=-1, din=0000000000000000 check_for_keys: keyboard scan failed However the keyboard works fine with the newer command: out: cmd=0x67: 03 96 67 00 00 00 00 00 in-header: 03 ef 00 00 0e 00 00 00 in-data: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ec_command_inptr: len=14, din=00000000f412df30 key_matrix_decode: num_keys = 0 0 valid keycodes found out: cmd=0x67: 03 96 67 00 00 00 00 00 in-header: 03 df 00 00 0e 00 00 00 in-data: 00 00 00 00 00 00 00 00 00 00 00 00 10 00 ec_command_inptr: len=14, din=00000000f412df30 key_matrix_decode: num_keys = 1 valid=1, row=4, col=11 keycode=28 1 valid keycodes found {0d} Signed-off-by: Alper Nebi Yasak Reviewed-by: Simon Glass

dm: Use driver_info index instead of pointer

2020-10-29T20:42:18Z

At present we use a 'node' pointer in the of-platadata phandle_n_arg structs. This is a pointer to the struct driver_info for a particular device, and we can use it to obtain the struct udevice pointer itself. Since we don't know the struct udevice pointer until it is allocated in memory, we have to fix up the phandle_n_arg.node at runtime. This is annoying since it requires that SPL's data is writable and adds a small amount of extra (generated) code in the dm_populate_phandle_data() function. Now that we can find a driver_info by its index, it is easier to put the index in the phandle_n_arg structures. Update dtoc to do this, add a new device_get_by_driver_info_idx() to look up a device by drive_info index and update the tests to match. Signed-off-by: Simon Glass
