license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

drivers: serial: esp32: Unify serial driver for esp32 & esp32s2 1) Allow use of interrup driven instance. ROM implementation could be selected via dts compatiable. 2) Use UART rx fifo and timeout interrupt for end of message detection. Added to decrease interrupts count on data reception 3) Use ESP_LL api. Signed-off-by: Pavlo Hamov <p.hamov@venstar.com>

kconfig: Turn pointless/confusing 'menuconfig's into 'config's Defining a symbol with 'menuconfig' just tells the menuconfig to display any dependent symbols that immediately follow it in a separate menu. 'menuconfig' has no effect on symbol values. Making a symbol that doesn't have any dependent symbols after it a 'menuconfig' should be avoided, because then you end up with an empty menu, which is shown as e.g. [*] Enable foo --- This is how it would be shown if there were children but they all happened to be invisible as well. With a regular 'config', it turns into [*] Enable foo Change all pointless 'menuconfig's to 'config's. See the section on 'menuconfig' on the Kconfig - Tips and Best Practices page as well.

config UART_ESP32
drivers: esp32: Add minimal UART driver based on ROM routines This is a minimal driver enabling console output during the port bringup. While the driver works, only one of the three UART devices are supported, and there isn't any way to change any parameters or use interrupts. This will most likely be superceded by a proper driver after the port has matured. Signed-off-by: Leandro Pereira <leandro.pereira@intel.com>

drivers: esp32: Add UART Driver with FIFO/Interrupt support - Fixes #3981 - Implement UART Polling functions - Implement UART Interrupt APIs - Remove dependency on esp32_rom_uart_xxx functions - Update Device tree with UART addresses and pin config - Update ESP32 UART KConfig Notes about implementation: - Interrupts now defined as a local macros, and should be removed later on, when interrupts for esp32 are supported in dts - Threshold interrupts are used for TX/RX - Reseting FIFOs using _RST bit will corrupt FIFO of UART2 when used for UART1 and vice-versa, so a generic way is used for all three UARTs - Old Silicon rev is not supported Signed-off-by: Mohamed ElShahawi <ExtremeGTX@hotmail.com>

help
drivers: esp32: uart: use hal functions In order to have Espressif SoCs working with the same uart drivers, all low level functions are now replaced to hal_espressif HAL calls. This also changes pinmux, gpio and uart init order to meet its dependencies. Signed-off-by: Sylvio Alves <sylvio.alves@espressif.com>
