if ARCH_CHIP_AM62X

menu "AM62x peripheral support"

config AM62X_TISCI
	bool "TISCI system controller (DM/TIFS) client"
	default n
	---help---
		Enable the AM62x TISCI client.  On K3 SoCs the A53 does not own
		device power, clocks, resets, or interrupt routing; those are
		requested from the DM/TIFS firmware over the TISCI protocol via the
		secure-proxy mailbox.  This driver provides the request helpers used
		by peripheral drivers to power on a block, enable its functional
		clock, release resets, and route its interrupt to the GIC.

if AM62X_TISCI

config AM62X_TISCI_HOST_ID
	int "TISCI host ID"
	default 12
	---help---
		Host ID this core presents to the DM/TIFS firmware.  Must match the
		host allocation in the firmware boardcfg.  12 is the standard A53
		HLOS host on AM62x.

config AM62X_TISCI_RX_THREAD
	int "Secure proxy RX (response) thread"
	default 12
	---help---
		Secure-proxy thread the firmware uses to send responses back to this
		host.

config AM62X_TISCI_TX_THREAD
	int "Secure proxy TX (request) thread"
	default 13
	---help---
		Secure-proxy thread this host uses to send requests to the firmware.

endif # AM62X_TISCI

config AM62X_GPIO
	bool "GPIO support"
	default n
	---help---
		Enable the AM62x main-domain GPIO controller driver, including
		basic GPIO input/output operations, pad-mux helper support, and
		per-pin interrupt callback dispatch for GPIO0/GPIO1.

config AM62X_GPIO_IRQ
	bool "GPIO interrupt (GIC) delivery"
	depends on AM62X_GPIO
	default n
	---help---
		Enable per-bank GPIO interrupt delivery through the GIC.  On AM62x
		the GPIO bank interrupts are routed through the main GPIO interrupt
		router, which must be programmed over TISCI (RM_IRQ_SET) before the
		GIC input line is valid.  Until that routing is implemented, leave
		this disabled: enabling an unrouted GIC line faults at boot.  GPIO
		input/output and the callback API still work without it.

config AM62X_I2C0
	bool "I2C0 support"
	depends on I2C
	default n

config AM62X_I2C1
	bool "I2C1 support"
	depends on I2C
	default n

config AM62X_I2C2
	bool "I2C2 support"
	depends on I2C
	default n

config AM62X_I2C3
	bool "I2C3 support"
	depends on I2C
	default n

config AM62X_I2CTIMEOMS
	int "I2C transfer timeout milliseconds"
	default 500
	depends on AM62X_I2C0 || AM62X_I2C1 || AM62X_I2C2 || AM62X_I2C3
