* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-1326-32/+32
| | | | | | | | | | | | This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

* cros_ec: Handling EC_CMD_GET_NEXT_EVENTHeinrich Schuchardt2020-11-141-0/+10
| | | | | | | | | | | | | | | | | | | 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.

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 <alpernebiyasak@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

| * dm: Use driver_info index instead of pointerSimon Glass2020-10-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FSP-S changes the ITSS priorities. The code that tries to save it before running FSP-S and restore it afterwards does not work as U-Boot relocates in between the save and restore. This means that the driver data saved before relocation is lost and the new driver just sees zeroes. Fix this by allocating space in the relocated memory for the ITSS data. Save it there and access it from the driver after relocation. This fixes interrupt handling on coral. Also drop the log_msg_ret() in irq_first_device_type() since this function can be called speculatively in places where we are not sure if there is an interrupt controller of that type. The resulting log errors are confusing when there is no error.

* dtoc: extend dtoc to use struct driver_info when linking nodesWalter Lozano2020-07-091-6/+4
| | | | | | | | | | | | | | | | In the current implementation, when dtoc parses a dtb to generate a struct platdata it converts the information related to linked nodes as pointers to struct platdata of destination nodes. By doing this, it makes difficult to get pointer to udevices created based on these information. This patch extends dtoc to use struct driver_info when populating information about linked nodes, which makes it easier to later get the devices created. In this context, reimplement functions like clk_get_by_index_platdata() which made use of the previous approach.

However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info.

* misc: i2c_eeprom: implement different probe test eeprom offsetEugen Hristev2020-05-281-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Because of this commit : 5ae84860b0 ("misc: i2c_eeprom: verify that the chip is functional at probe()") at probe time, each eeprom is tested for read at offset 0. The Atmel AT24MAC402 eeprom has different mapping. One i2c slave address is used for the lower 0x80 bytes and another i2c slave address is used for the upper 0x80 bytes. Because of this basically the i2c master sees 2 different slaves. We need the upper bytes because we read the unique MAC address from this EEPROM area. However this implies that our slave address will return error on reads from address 0x0 to 0x80. To solve this, implemented an offset field inside platform data that is by default 0 (as it is used now), but can be changed in the compatible table. The probe function will now read at this offset and use it, instead of blindly checking offset 0. This will fix the regression noticed on these EEPROMs since the commit abovementioned that introduces the probe failed issue.
