Common data structures are introduced here. Signed-off-by: Martyn Welch Signed-off-by: Hari Nagalla --- Changes since v5: - Created a separate patch for data structures to ease review Changes since v6: - Reworded 'split' to 'move' as the common data structures between DSP and M4 remote rpoc drivers are moved into common driver. link to v6: https://lore.kernel.org/all/20230913111644.29889-3-hnagalla@ti.com/ drivers/remoteproc/ti_k3_common.h | 107 ++++++++++++++++++++++++++++++ 1 file changed, 107 insertions(+) create mode 100644 drivers/remoteproc/ti_k3_common.h diff --git a/drivers/remoteproc/ti_k3_common.h b/drivers/remoteproc/ti_k3_common.h new file mode 100644 index 000000000000..f1bab83dd0fc --- /dev/null +++ b/drivers/remoteproc/ti_k3_common.h @@ -0,0 +1,107 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +/* + * TI K3 Remote Processor(s) driver common code + * + * Refactored from ti_k3_dsp_remoteproc.c. + * + * ti_k3_dsp_remoteproc.c: + * Copyright (C) 2018-2022 Texas Instruments Incorporated - https://www.ti.com/ + * Suman Anna + */ + +#ifndef REMOTEPROC_TI_K3_COMMON_H +#define REMOTEPROC_TI_K3_COMMON_H + +#define KEYSTONE_RPROC_LOCAL_ADDRESS_MASK (SZ_16M - 1) + +/** + * struct k3_rproc_mem - internal memory structure + * @cpu_addr: MPU virtual address of the memory region + * @bus_addr: Bus address used to access the memory region + * @dev_addr: Device address of the memory region from remote processor view + * @size: Size of the memory region + */ +struct k3_rproc_mem { + void __iomem *cpu_addr; + phys_addr_t bus_addr; + u32 dev_addr; + size_t size; +}; + +/** + * struct k3_rproc_mem_data - memory definitions for a remote processor + * @name: name for this memory entry + * @dev_addr: device address for the memory entry + */ +struct k3_rproc_mem_data { + const char *name; + const u32 dev_addr; +}; + +/** + * struct k3_rproc_dev_data - device data structure for a remote processor + * @mems: pointer to memory definitions for a remote processor + * @num_mems: number of memory regions in @mems + * @boot_align_addr: boot vector address alignment granularity + * @uses_lreset: flag to denote the need for local reset management + */ +struct k3_rproc_dev_data { + const struct k3_rproc_mem_data *mems; + u32 num_mems; + u32 boot_align_addr; + bool uses_lreset; +}; + +/** + * struct k3_rproc - k3 remote processor driver structure + * @dev: cached device pointer + * @rproc: remoteproc device handle + * @mem: internal memory regions data + * @num_mems: number of internal memory regions + * @rmem: reserved memory regions data + * @num_rmems: number of reserved memory regions + * @reset: reset control handle + * @data: pointer to device data + * @tsp: TI-SCI processor control handle + * @ti_sci: TI-SCI handle + * @ti_sci_id: TI-SCI device identifier + * @mbox: mailbox channel handle + * @client: mailbox client to request the mailbox channel + */ +struct k3_rproc { + struct device *dev; + struct rproc *rproc; + struct k3_rproc_mem *mem; + int num_mems; + struct k3_rproc_mem *sram; + int num_sram; + struct k3_rproc_mem *rmem; + int num_rmems; + struct reset_control *reset; + const struct k3_rproc_dev_data *data; + struct ti_sci_proc *tsp; + const struct ti_sci_handle *ti_sci; + u32 ti_sci_id; + struct mbox_chan *mbox; + struct mbox_client client; +}; + +void k3_rproc_kick(struct rproc *rproc, int vqid); +int k3_rproc_reset(struct k3_rproc *kproc); +int k3_rproc_release(struct k3_rproc *kproc); +int k3_rproc_request_mbox(struct rproc *rproc); +int k3_rproc_prepare(struct rproc *rproc); +int k3_rproc_unprepare(struct rproc *rproc); +struct resource_table *k3_get_loaded_rsc_table(struct rproc *rproc, + size_t *rsc_table_sz); +void *k3_rproc_da_to_va(struct rproc *rproc, u64 da, size_t len, + bool *is_iomem); +int k3_rproc_of_get_memories(struct platform_device *pdev, + struct k3_rproc *kproc); +int k3_rproc_of_get_sram_memories(struct platform_device *pdev, + struct k3_rproc *kproc); +int k3_reserved_mem_init(struct k3_rproc *kproc); +void k3_reserved_mem_exit(struct k3_rproc *kproc); +struct ti_sci_proc *k3_rproc_of_get_tsp(struct device *dev, + const struct ti_sci_handle *sci); +#endif /* REMOTEPROC_TI_K3_COMMON_H */
